3/8-16 x 1/4 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert combines cup-point bite, internal hex drive access, and nylon prevailing torque. The cup point may leave a witness mark depending on shaft material and installation conditions, while the insert works in the threaded engagement. The stainless construction supports equipment that needs a clean finish without claiming 316-level chloride performance.
Typical uses include marine-adjacent hardware after chloride review, collars, and component retention, where the set screw must hold position without an external head. For 316 stainless with a nylon insert, treat the requirement as a non-catalog request that Cold Headers can quote.
Cold Headers brings long-running socket fastener knowledge to cup point set screw quoting and cross-checking. Review the thread size, length, hex key size, point style, and set-screw pellet location before matching the part to a service record or drawing.
