5/16-18 x 1 3/4 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is selected when stainless hardware and thread-friction locking are needed in the same fastener. The insert is positioned in the threaded body so the screw can develop prevailing torque during engagement.
In outdoor control enclosures, panel hardware, or instrument mounting brackets, the internal hex drive keeps installation compact while the insert adds thread-friction locking action. Slight magnetism from cold working can be normal for 18-8 stainless, so selection should reflect the actual assembly environment and mating hardware.
When chloride or saltwater exposure controls material selection, ask about 316 stainless nylon-insert cap screws as a non-catalog request. Need the pellet in a non-catalog size or position? In-house pelletizing gives Cold Headers a practical route for special requests.
