Product Description

Norwood Screw Machine has been an approved supplier of military hardware for over 55 years supplying shoulder screws for all variations of helmets including ACH, ECH, LWH, MICH & PASGT.

Precision shoulder screws, also known as shoulder bolts, are utilized in many applications. Rotation of the shoulder screw can move a corresponding part. Moving parts of an engine are assembled using shoulder screws. The socket heads of socket shoulder screws are designed to facilitate fastening at high torque levels. Pulleys and sprockets are connected using shoulder screws, which enables them to rotate.

The shoulder length and diameter can govern the speed of the movement and provide unlimited fastening options.  Also known as stripper bolts, they are used to attach stripper plates. Standard  precision shoulder screws are available in decimal and metric configurations. Precision-grade shoulder screws are manufactured by Norwood to guarantee a reliable performance. Precision-grade shoulder screws feature specific tolerances on diameters, lengths, heads and threads.

Precision shoulder screws are often used in punch-and-die mechanisms to support any movement during the punching process. In plastic injection mold sets, shoulder bolts are used to support the movement of the dies in the machine. These screws help in the movement of the dies to open and close them during the injection molding process.
