M20 x 25 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is frequently selected where a sliding, rotating, or reciprocating component needs a shoulder surface to ride against. This format is different from standard socket head cap screws because the shoulder is intended to carry the locating or motion-control role. Common uses include metric automation systems, die sets, stripper plates, and fixture rebuilds; related sourcing may also include European machinery. Repair technicians may source this product when service work calls for the same metric shoulder pair used in the original assembly. The result is a serviceable metric shoulder screw for controlled movement, fixture alignment, and OEM production support. It can also support guide mechanisms, fixture stops, and replacement maintenance where a consistent shoulder surface is part of the design.
