3/4 x 6 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert provides a shoulder-bearing surface for guided components and a nylon insert for added thread retention. The shoulder provides the controlled interface, the 5/8-11 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. Thread length is nominal, so review the drawing or service record when replacing an existing die component.

Cold Headers assists with specialty socket products, replacement fasteners, and nylon-insert shoulder screw requirements. Confirm the working shoulder length, tapped-hole depth, hex key clearance, and nylon insert position during replacement sourcing.
