5/8-11 x 1/2 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is a stainless socket cap screw for assemblies that combine cleaning exposure with motion or vibration. The insert is positioned in the threaded body so the screw can develop prevailing torque during engagement.

Typical applications include pharmaceutical fixtures, inspection stations, and clean industrial work cells, where the exact thread and length help match drawings, service records, and replacement needs. The nylon element gives the joint a locking feature, but it also limits service temperature compared with an all-metal socket screw.

For countersunk installations, 18-8 Flat Head Socket Cap Screws with Nylon Insert keep the locking feature in a different head style. Need the pellet in a non-catalog size or position? In-house pelletizing gives Cold Headers a practical route for special requests.
