M6 x 90 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is a metric alloy steel shoulder screw where the ground shoulder does the locating work. Order by the shoulder size and shoulder length; the smaller thread below the shoulder is intentional under ISO 7379 geometry.

Mold slides, lifters, and guided tooling details use shoulder screws where the shoulder acts as the controlled sliding surface. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution.

Cold Headers helps distributors, toolrooms, and maintenance teams keep shoulder diameter, length, and thread pairing aligned. ISO 7379 catalog nominals often list 6.5 mm here; this stocked 6 mm shoulder is the North American metric tooling variant. Alloy Steel Socket Head Stripper Bolts with Nylon Insert add a self-locking thread feature for vibration service.
