5/8 x 2 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert offers a practical solution when tooling or machine components need both socket-drive retention and a functional shoulder. The important engineering feature is the shoulder, which supports positioning and movement while the threaded end retains the fastener. Typical applications include press tooling, guided plate movement, stop blocks, and linkage assemblies. The nylon insert is useful in assemblies where a shoulder screw or stripper bolt must stay seated while nearby components move or cycle. Engineers can use the shoulder-size pair to match the bearing surface and travel requirement without changing the dimensional convention. The design is useful when the fastener is part of the positioning system rather than only a threaded clamping point. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
