S-94035A112 2-56 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
• Precise component alignment ensured by the smooth, accurately machined shoulder with controlled diameter and length tolerances
• High-strength performance with 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing applications
• Easy, secure installation using a standard 5/64" hex key, preventing tool slippage and damage to the socket head
• Consistent thread engagement provided by the 2-56 UNC coarse thread with Class 2A fit, reducing cross-threading risks
• Broad regulatory compliance meeting RoHS 3 and REACH standards for use in regulated industries and global markets
• Durable, long-lasting finish that maintains appearance and function while resisting wear and chemical exposure

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and mounting challenges in industrial applications. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to corrosion, oxidation, and chemical degradation, making it suitable for machinery, electronics, and automotive assemblies exposed to demanding conditions. The 3/32" shoulder diameter with precise tolerances acts as a reliable pivot, bearing surface, or locating dowel, ensuring accurate part positioning and reducing assembly errors. The 2-56 UNC coarse thread and Class 2A thread fit facilitate quick, secure fastening in right-hand thread applications, while the socket head design allows for compact installations with standard hex tools. This screw delivers engineering value by enhancing assembly precision, durability, and maintenance efficiency in precision equipment and automated systems.

Specification Summary & Compliance
