17-4 PH Shoulder Screw

17-4 PH Shoulder Bolts


17-4 PH shoulder bolts are made from a precipitation hardened stainless steel most known for its exceptional strength and its ability to maintain its mechanical properties to 600°F. Compared to 316 stainless steel, 17-4 PH bolts yield strength is up over 4 times greater. When compared to Duplex 2205 bolts, the yield strength of 17-4 PH can be up to 2-½ times greater.

17-4 shoulder screws are available in 8 different aged (precipitation hardened) conditions offering a variety of mechanical properties

17-4PH Shoulder Bolt Features and Benefits


17-4PH shoulder bolts, also called stripper bolts are a unique fastener with three main parts: head, shoulder, and thread. The head has the largest diameter and is where the torque is applied, typically with a socket driver. The shoulder is smooth and unthreaded, and has a set diameter and length. The shoulder’s role is to act as a shaft or dowel for rotating parts, axles for rolling parts, guides for sliding elements, and pivot points. The final part of a 17-4PH shoulder bolt is the threaded shaft. The threaded portion of a shoulder bolt has a major diameter slightly smaller than the shoulder diameter.
