M12 x 70 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) supports metric pivots, rollers, guides, and travel posts where the shoulder is the bearing surface. Order by the shoulder size and shoulder length; the smaller thread below the shoulder is intentional under ISO 7379 geometry.

Sensor mounts, brackets, and standoffs use metric shoulder screws when spacing and rotation need to be controlled. 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 13 mm here; this hard-to-find 12 mm shoulder is a stocked variant used in North American metric tooling. Alloy Steel Socket Head Stripper Bolts with Nylon Insert add a self-locking thread feature for vibration service. 316 or other special-material metric shoulder screws are non-catalog quote requests when the print requires that material.
