M16 x 30 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is a socket head shoulder screw for die, mold, and machine motion built around a 16 mm shoulder. This is a locating and motion component, not a substitute for a clamp-load cap screw when the print calls for clamping.

Guide posts on metric machinery use shoulder screws to align covers, slides, fixture details, and moving stops. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution.

When the length or diameter is uncommon, Cold Headers can help review the metric shoulder screw requirement by exact size.
