5/8-11 x 7/8 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is built for drawings that call for both stainless material and prevailing-torque thread locking. Its locking element supports service where a standard all-metal cap screw may need an added thread-locking feature.
Use it for wash-bay equipment, maintenance fixtures, or replacement assemblies after confirming thread engagement, drive access, and the mating material. The 18% chromium and 8% nickel austenitic stainless material is used for general corrosion resistance and a clean appearance in ordinary industrial environments.
For countersunk installations, 18-8 Flat Head Socket Cap Screws with Nylon Insert keep the locking feature in a different head style. Cold Headers installs nylon inserts in-house for supported socket-cap configurations, with odd-size sourcing handled through the quote process.
