M12 (16mm) x 40mm Socket Shoulder Screw (ISO 7379) | 12.9 Steel
Manufactured to ISO 7379, this M12 (16mm) x 40mm Socket Shoulder Screw is suited to mechanical joints where the shoulder must guide movement before the thread clamps the part. It suits bearing shoulder bolt requirements where the shoulder size matters as much as the thread.
The 12.9 steel material is intended for high strength mechanical assemblies where tightening force and load capacity are important. The defined shoulder length separates moving components from the clamped joint, reducing the need for extra sleeves or spacers.
