1/2 x 1 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert is sized for tooling and fixture work where the shoulder is the operating surface, not merely a fastener shank. The shoulder provides the controlled interface, the 3/8-16 threaded end retains the part, and the socket head keeps installation access available from the top side. That nylon insert helps the screw resist backing out during cyclic shock, vibration, or press operation without implying permanent locking.
Designers often review this size for press tooling, blanking dies, stripper plate screws, and controlled-return hardware where a plain threaded screw would not provide a proper guide or pivot surface. The nylon element limits service temperature compared to an all-metal screw; ask about plain stripper bolts for hot tooling. When the application calls for stainless material instead of alloy steel, review 18-8 Stainless Steel Stripper Bolts.
Cold Headers supports die repair, OEM sourcing, and distributor requests for uncommon shoulder lengths and nylon-insert configurations. The size callout should be matched to the travel requirement, shoulder bearing surface, tapped hole, and access for the hex key.
