M20 x 16 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) gives metric tooling one fastener with a retaining head, working shoulder, and anchoring thread. The head retains the part, the shoulder bears and locates, and the thread secures the fastener in the tapped hole.

Metric linkage pivots use this style where the joint needs a smooth shoulder rather than threads through the moving member. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution.

Cold Headers keeps metric shoulder screws separate from socket head cap screws so the locating function stays clear. Alloy Steel Metric Socket Head Cap Screws are the clamping fastener choice when a metric print does not need a shoulder.
