The 9342-K Tiny Adjustment Screw is perfect if you need to build miniature mounts or positioners. We use these same screw sets in our pint-sized mounts, so you know you're getting the best quality. This ball tip adjustment screw has 80 threads per inch and 5.1 mm of travel with Hex-key adjustment. Built with the same proprietary process as our 1/4-80 screw sets, these screws feature tight tolerances and no excess grease, resulting in actuators with very smooth movement, high precision, and exceptional long-term and thermal stability.
