Installation of Thread Matched Adjustment Screws and Nuts
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.
Innovative Manufacturing Process for Long-term Stability
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.
Locking and Non-Locking Versions
Thread-Matched Adjustment Screws are available in both locking and non locking versions. Use the locking version to discourage unwanted adjustment, use the non-locking version when a more compact screw is needed.
