MP159 Shoulder Bolts
Brand RAYCHIN
Product origin China
Delivery time 5-35 DAYS
As aerospace engineering advances, so must the materials to meet the technological requirements of this industry. Bolts made from MP159 have been developed to provide a solution to high temperature, high strength components. MP159 shoulder bolts offer strength capabilities similar to other Cobalt Alloys (MP35N) but can be used at much higher temperatures - up to 1100°F, compared to MP35N’s usable limit of 800F. In addition, MP159 bolts can be used beyond 1100°F in short term situations.

MP159 Shoulder Bolt Features and Benefits
MP159 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 MP159 shoulder bolt is the threaded shaft. The threaded portion of a shoulder bolt has a major diameter slightly smaller than the shoulder diameter.
