The F3SS series adjuster screws are ideal for limited space applications that require fine (250 μm/rev) resolution. Each threaded component is individually tested with a master gauge set that ensures the inter-changeability of our fine adjustment components. The hex adjusters feature a 1.5 mm hex socket, which provides a simple way to make fine adjustments. The fine adjuster screws come lubricated to ensure smooth mating into compatible components.

The assembly process begins by producing the appropriate sized mating hole for the threaded bushing. Given the close fit between the threaded bushing and the mating adjuster screw, we caution against using a press fit to assemble these products. For our own production needs, we use a permanent anaerobic adhesive that provides excellent long-term performance.

We recommend using Loctite Anaerobic Adhesive product number 680 or equivalent. In order to ensure maximum strength between the bonded parts, we strongly urge the user to follow carefully the instructions provided by Loctite, which specify the amount of clearance between the threaded bushing and the mounting plate. The most common source of failure is not allowing for the proper clearance between the parts being bonded since this clearance provides for the proper volume of adhesive.

As shown in Figure 1, the flange on the mating bushing is designed to support the axial load of the screw and bushing assembly.

When assembling, apply a small amount of the Loctite adhesive to both threaded bushings and the mounting plate and ensure a uniform distribution of the adhesive around the perimeter of the parts before assembly. After insertion, remove any excess adhesive from around the part.
