An engineered high temperature resistant steelshoulder bolt s

  • Excellent high temperature stability
  • Very oxidation and carburization resistant to 2100°F
  • Good resistance to thermal shock and quenching
  • Alloy 330 shoulder bolt features and benefits

Alloy 330 shoulder bolts are specifically designed for high temperature furnace applications. Alloy 330 bolts unique combination of properties allow 330 bolts to handle thermal shock from quenching, be oxidation and carburization resistant as well as handle thermal cycling well.  As a result, alloy 330 shoulder bolts are found in high temperature applications like vacuum furnaces, heat treating and brazing applications.

Alloy 330 Shoulder Bolt Features and Benefits

Alloy 330 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 an alloy 330 shoulder bolt is the threaded shaft. The threaded portion of a shoulder bolt has a major diameter slightly smaller than the shoulder diameter.
