The F3ES series hex adjustment screws are manufactured from 303 Stainless Steel and come lubricated for smooth mating with compatible components. The extremely fine 0.20 mm per revolution thread precludes the use of taps to produce threaded mating parts for this series of screws. The F3ESK1 removable adjustment knob threads on to an M3 x 0.20 threaded adjuster and provides a means to make fine adjustment without a hex key. Threaded bushings and lock nuts are available to further aid the incorporation of fine adjustment in your application.

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.
