S-96126A159 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel and passivated finish, ideal for harsh industrial environments.
• Precise alignment and smooth rotation ensured by a 2" shoulder with tight length tolerance (±0.002") and smooth texture.
• High mechanical strength and durability from 70,000 psi tensile strength and Rockwell B79 hardness for reliable performance.
• Secure and efficient installation using a 3/32" hex socket drive, preventing cam-out and ensuring consistent torque application.
• Accurate and reliable thread engagement with UNC coarse threads and Class 2A fit, reducing assembly errors.
• Compliance with environmental and safety standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 316 Stainless Steel material, combined with a passivated finish, provides exceptional resistance to corrosion and chemicals, making it suitable for demanding environments like marine, chemical processing, and food machinery. The 2" shoulder length with minimal tolerances ensures exact component spacing and smooth pivoting in applications such as rotating shafts, linkages, and bearing mounts. Its hex socket head allows for high-torque installation in confined spaces, while the coarse UNC threads and Class 2A fit facilitate quick, secure fastening, reducing downtime and maintenance in industrial equipment.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent engagement and a shoulder diameter tolerance of -0.001" to 0" for accurate alignment. It meets manufacturing specifications for UNC threads and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for global industrial applications.
