Is it possible for us to just buy TC4 without all the screw drivers/wrenches? We basically just want to organize all the screw drivers/wrenches that we currently have and not intend to bother getting any extra screw drivers. Thank you.

Die Schlüssel sind sehr lose in der Halterung und fallen sofort raus wenn man sie bewegt. Eine Halterung aus Kunststoff wäre hier vielleicht besser, da könnten die Bohrungen enger sein und die Schlüssel würde darin halten (siehe SwissTools Set PB210 H, da funktioniert das super)

It cannot be used for Z-theta adjuster for fiberport collimator, since it collides with fiber connector. It would be very good if smaller hex key thumbscrews are available for fiberport collimator, as an alternative of L-shaped hex keys (falls off easily, collide with fiber, hard to put in a hole).

I was a little surprised at how short these hex keys are, but I was more shocked that the hex keys fit so poorly into the holder. When retrieving one key it's almost impossible to keep the others in place.

Hello, It would be good if you would sell *only* the top/holder plate, so that this nice tool stand can be built with on-hand posts, and for use with one's preferred hex keys. As it is now I'm going to print a couple out of CF-PLA, but I'd rather just buy them.

I love HKTS drivers a lot and use 0.050" and 5/64" very frequently. We also have a lot of screw tightening jobs in the lab that involves 3/32" screws. It will be really nice if you can add a 3/32" option to the already amazing HKTS series.

Jonathan Twichell  (posted 2020-08-21 08:38:45.253)
They need color coded rings The Bondhaus drivers at least have sizes imprinted, thorlabs ones do not. I often wish for a universal joint at the tip, or a bendable but rotationally stiff section (two tight-wound springs wound in opposite direction nested?) or a flexure (hard to get enough angle but you guys are clever)

Hello, Would you be able to offer a 4-pack of 2 mm (metric) hex key thumb screws, or at least offer them separately from the whole range of sizes? We very often need the 2 mm screws and I am pretty sure they were offered separately last year (which was great). Best regards, JG Brisset
YLohia  (posted 2020-03-12 08:46:47.0)
Hello JG, we currently offer the HKTS-5/64, which is a four-pack of the 2 mm hex key thumb screws. Please note that this is a universal thread, so it works with both 2 mm (metric) and 5/64" (imperial).

Bram Mooij  (posted 2019-10-04 10:33:02.197)
I am a bit disappointed by this set. Our lab has a lot of these sets (also the imperial version). The grips are too small, so if any force is required they don't work very well. This holds especially for the 5mm and 3mm variants. Also, I miss the rotating end on the the 2mm and 1.5mm balldrivers. This is something that companies like Wera and Wiha do provide and help a lot in some cases. Their offerings are also much stronger, a lot of our lab's 0.05 inch and 1.5mm hex keys are a bit bent. I personally never order tools from Thorlabs because I prefer the alternatives elsewhere. If you would stock Wera, Wiha or similar I would order tools from Thorlabs. Do you have any plans to supply alternatives?
YLohia  (posted 2019-10-04 11:13:18.0)
Hello, thank you for your feedback. We are sorry to hear that the ball drivers in the BD-KIT do not hold up to the quality we strive for in every Thorlabs product. Currently, we source our ball drivers from Bondhus and have not made any plans of switching suppliers. That being said, I have posted your feedback on our internal product engineering forum for further discussion.

The interchangeable ball driver (MBD) is very difficult to use. The bits fit so tightly in the handle that it takes more time and effort to use it than to just go get the other ball drivers from across the lab. I know it's a delicate balance between them fitting snugly enough to stay in and not being awful to remove them, but this product could use another round of refinements. Maybe magnets, softer material, etc? I never use mine, unfortunately. Thanks for listening!
YLohia  (posted 2018-10-04 08:50:21.0)
Hello, thank you for your feedback. We are sorry to hear that the MBD is not meeting your expectations. At Thorlabs, we continuously strive to make our customers' experience in the lab better. We appreciate your suggestions and I have shared your feedback with the engineers responsible for this product for further consideration.

hyperlinking the images in the banner to the product description might be useful. For example clicking on the image of HKTS-9/64 could take us to the product (not the product page, that would be too specific) and we could look for the exact size/product on the list.

The BT17 and BT17/M are great, but very expensive because of the airfreight costs. Can you ship unassembled to reduce costs? We'd be interested in buying in packs of 5 in that case, and particularly if we could buy the stands only without bottles and ball drivers.
llamb  (posted 2018-06-11 02:56:09.0)
Thank you for contacting Thorlabs. Unfortunately we are not able to offer these kits disassembled as it would not be cost effective for the user. We may be able to offer the stand on its own however, without the balldrivers and bottles. I will reach out to you directly to discuss a possible quote.

People are always losing and stealing my ball drivers! Would it be possible to order ball drivers individually, as opposed to by-the-set? The M1.5 seems to be particularly coveted by thieves. (I could buy from another source, but then they wouldn't match your set. I even tried the manufacturer's website, but to no avail.)

Hi, This is a constant user of THORLABS(c) mechanichs speaking. A lot of times i have regreted about a lack of T-shaped hex ball screw-drivers, that I have seen in hands of COHERENT field engineers, cause usual screw-drivers are not suitable for a strong tightening in difficult high-density schemes. I would like to see them in the product catalogue of THORLABS, so i could buy it. Best wishes. Pavel

Response from Tim at Thorlabs: The current design is made to be compatible with the standard 2” edge spacing found on our optical tables ends and breadboards without being inconveniently large on smaller breadboards. The edge spacing on optical table sides can vary beyond 2.5”. Based on your feedback we are reviewing this design to see if changes would make this product more convenient.
user  (posted 2012-09-11 17:34:47.0)
The TC4 does not fit on your optical tables. It can be attached to the ends but when attached to the sides of the table the holes for the ball drivers interfere with the table top. The slots need to extend another 0.5".

Dear Sir, Given the complexity of my optomechanical setup, I need all my apparatus to be as tight as possible. Trying to achieve this, however, I destroyed several screws, post and post holders. Do you sell torque wrenches, or would you recommand any hex torque wrenches to use with your products, to maximize tightening while avoiding destruction of screws and threads ? Thank you very much. Best regards.

There seems to be room for a second 3/16" ball driver near the mounting slots, as well as 2 more 5/64" drivers near the current one. Having these extra parking spaces would be great, no need to fill them when selling the complete kit, just give us more parking.

Response from Buki at Thorlabs: Thank you for your feedback. I will pass on your idea to our production team. As a short term solution, I could send you another BD-KIT, or I could send you the HK050, which is a 10 pack of the 0.05” hex key. If a hex key is not convenient for you, you could purchase the ball driver from a hardware store.
atkinsond  (posted 2011-07-15 12:36:40.0)

Which size of hex key is required to do up the #4-40 setscrews in the end of Thorlabs 30 mm cage rods such as the ER1? I used to have a ball driver lying around in the lab which was really handy to have around when working with cage system components. Do you sell a ball driver for these tiny setscrews?

Response from Javier at Thorlabs to bpatterson: Thank you very much for contacting us. We might be able to offer certain hex key and ball drivers sizes individually. I will contact you directly to get your requirements.
bpatterson  (posted 2011-05-16 18:46:02.0)
You only have certain sizes of individual ball drivers listed. Can I purchase any size individually?

A response from Adam at Thorlabs to Rziegler: I agree that this type of modification would be a good idea. I too have had issues with these holders when using them on a crowded table. I will pass this along to our engineer department as a customer inspired idea. A short term fix for this problem may be to clamp the TC2 to the table using a few CL5.
rziegler  (posted 2010-02-17 14:54:19.0)
Im assuming the base is weighted. Any thoughts on making it magnetic? This would help keep it from being pushed off a crowded table...

Respnse from Laurie at Thorlabs to rwilliams: The stands can be purchased separately, but a special order needs to be requested through our tech support department. Please call them at 973-300-3000 and ask to speak to an applications engineer. Thank you for your interest in these organizational items.
rwilliams  (posted 2008-03-11 14:56:28.0)
Can I get the stand only for TC2 and BT17? I have lots of the tools already that I need to organize. Id be looking for 3 copies of each. regards, Rich

Among the most essential general-purpose tools in any optics laboratory, balldrivers are used to secure standard cap screws and setscrews in optomechanical assemblies. Balldrivers can be purchased individually or in kits. See the tables to the right for the balldrivers included with each kit.

Unlike standard hex wrenches, the unique hex ball design of the balldriver tips allows them to operate at angles, which is ideal for tightening or loosening screws in hard-to-reach places. Imperial balldrivers have a yellow handle, while metric balldrivers have a red handle. All balldrivers have a high-strength steel alloy blade. The BD-3/16L and BD-5ML have an extra long 8" (20.3 cm) shaft with an overall length of 11" (27.9 cm), including the handle. For the lengths of all of our balldrivers, see the Tool Dimensions tab above.

The BD-1.3M is labeled as a 1.27 mm balldriver. Please note that the industry standard is to round 1.27 mm hex measurements to 1.3 mm, and thus the BD-1.3M is compatible with all 1.3 mm hex components. For compatibility information between other balldrivers/hex keys and screws, see the Hex Key Compatibility tab above.

  • Interchangeable Bits Stored in Handle
  • Easily Swap Bit Sizes
  • Imperial and Metric Options Available

The MBD(/M) Interchangeable Balldriver Sets are 8" (20.3 cm) long from the tip of the bit to the end of the handle and have 3" (7.5 cm) long steel alloy bits. The bit selection in each set was specially chosen to fit the most common hex sizes used in Thorlabs' products. Unlike standard hex wrenches, the unique hex ball design of the balldriver tip allows it to operate at angles, which is ideal for hard-to-reach places.

The MBD set contains seven interchangeable bits (see the table to the right). Six of these bits are stored securely in the yellow handle, while the seventh is pre-inserted into the main shaft, ready for use. The MBD/M set contains six interchangeable bits, which should not be stored in the red handle at the same time. One bit should always be kept in the shaft so that the others can be removed with ease.

To change a bit, firmly pull the bit out of the shaft. Insert the top of the bit that was just removed into the hole on the bottom of the handle that houses the bit you would like to use next. Tightly grip the handle and push the old bit into the hole, which will cause the new bit to come out of a hole located at the base of the shaft, as indicated in the video to the right. Pull out the new bit, and slide the old one the rest of the way in.

  • Available in Popular Imperial and Metric Sizes
  • Red Anodized Adjustment Knob with Engraved Hex Size
  • Replaceable Hex Tip
  • Individual Sizes Sold in Packs of Four
  • Kits Available with Multiple Sizes

Hex Key Thumbscrews allow for quick, low-profile adjustment of hex-driven actuators, cap screws, and setscrews. Unlike balldrivers, they can be left in the screw's hex socket between adjustments for convenience. Each size comes in a pack of four thumbscrews. We offer two kits containing one hex key of each size. The HKTS-KIT imperial kit contains 0.050", 5/64", 1/8", 9/64", and 3/16" sizes, and the HKTS-KIT/M metric kit contains 1.3 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, and 5 mm sizes.

The 5/64" size is especially useful for adjusting our hex-driven kinematic mounts (see photo to the right). In addition, this size is fully compatible with 2.0 mm hex sockets. The 0.050" size is fully compatible with 1.3 mm hex sockets.

Each thumbscrew incorporates an 8-32 setscrew with a 5/64" [2.0 mm] hex that secures the replaceable hex bit, which can be reversed if the tip is stripped. Contact Tech Support to order replacement hex key bits.
