Socket Head Shoulder Screws

Click image to enlarge
Hex socket head shoulder screws, also known as shoulder bolts and stripper bolts, are precision fasteners that have a hex-shaped socket in a round head, an unthreaded shoulder and a threaded tip. The unthreaded portion of the shoulder screw serves as a spacer and bearing surface for use with rotating parts and as linear guides.
Precision shoulder bolts are frequently manufactured from 303 or 416 stainless steel. They can be made in many other materials including hardened alloy steel, mild steel, brass and even plastics. They are typically installed using a hex wrench, screw driver or hexalobular (star) driver which provide maximum wrenching strength to ensure a secure attachment.

Hex head shoulder screws can also be used as a stationary linear guide for guiding and aligning parts and components.
Shoulder bolts are highly versatile and suitable for a wide range of applications, including: 
  • Attaching gears, pulleys, sprockets, bearings and other components
  • Assembling medical and orthopedic equipment
  • Aligning punches and molds
  • Building custom Cam Followers
  • Installing printer heads and other electronic components

Precision Shoulder Screws for Strong and Reliable Fastening

Ondrives.US provides socket head shoulder screws in inch and metric sizes and in materials including martensitic 416 stainless steel and austenitic 303 stainless steel. 416 stainless steel is magnetic and heat treated to increase its hardness and tensile strength. 303 stainless steel provides superior corrosion resistance for use in severe environments and has slightly lower tensile strength. We also offer shoulder bolts that feature thread locking via nylon pellet or strip and provide optional head seals using a special coating or O-ring.
