The 0.5 inch (12.7 mm) 9313-K Adjustment Screw provides smooth, wobble-free adjustment combined with exceptional long-term stability and low susceptibility to thermal variation. It is the same 1/4-80 precision screw used in our optic mounts and allows you to build your own mounts or positioners. In addition to a travel of 0.5 inch (12.7 mm); the screw has a ball tip, unbraked brass bushing, and is Hex-key adjusted.
New Focus precision nuts are designed for easy installation in your equipment. We recommend using an adhesive when mounting the nut in a slip-fit hole. Do not press-fit the nut or it may distort. It is important to mount the nut such that any axial force is taken up by the mounting flange. Axial force should not be carried by the adhesive. We recommend using Loctite® Product 609 anaerobic retaining adhesive. It is essential that both surfaces be completely free of grease for proper curing of the adhesive.
Outstanding positional and thermal performance is achieved using a proprietary assembly process. This assembly process uses tightly toleranced subcomponents and the ideal amount of lubrication. The small amount of lubrication is optimized to mitigate the effects of hysteresis and long-term creep caused by lubricant migration.
