1/2-13 x 1 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. Slight magnetism from cold working can be normal for 18-8 stainless, so verify the material requirement against the actual assembly.
Typical uses include pump and mixer shafts, drive collars, and equipment repairs, 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 installs the locking pellet in-house on supported socket set screw sizes, with odd-size requests handled through quoting. 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.
