5/16"-32 Locking Hex Nut Included
Total Length: 0.5"
The N100L5P ultra-fine adjuster nut is made from 510 Phosphor Bronze, which is vacuum rated for 10-6 Torr, and includes a removable nut and sleeve. The sleeve has both internal 3/16"-100 and external 5/16"-32 threads, and can be mounted into a clearance hole. Once the sleeve is in place the locking nut can be used to clamp the sleeve into place. This sleeve can then be used with a 3/16"-100 fine adjuster for fine adjustment in a variety of applications where threaded bushings are not suitable. For vacuum applications, we recommend a thorough ultrasonic cleaning to remove any grease or particulates prior to use.
The N100B2P and F19SS series threaded bushings are designed for slip fit applications, as the 3/16"-100 threading tolerances are too tight for press fit. The recommended bore diameter for our N100 bushings is 0.242" +0.001"/-0.000", and for our F19 bushings is 0.290" +0.001/-0.000". Each bushing is made of phosphor bronze in order to prevent damage to the fine adjusters. Phosphor bronze offers advantages like vacuum compatibility over brass. For vacuum applications, we recommend a thorough ultrasonic cleaning to remove any grease or particulates prior to use.
Material: 510 Phosphor Bronze
Vacuum Compatible: 10-6 Torr
