S-94035A154 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish for long-lasting performance in harsh environments.
• Precise alignment and secure pivoting ensured by the 3/4" shoulder with tight diameter and length tolerances for reduced assembly vibration.
• High-strength durability with 70,000 psi tensile strength and Rockwell B55 hardness to withstand heavy loads and repeated use.
• Easy installation and removal using a standard 3/32" hex key drive, providing reliable torque transfer in confined spaces.
• Consistent thread engagement with Class 2A UNC coarse threads for quick assembly and reduced cross-threading risks.
• Compliance with global regulations including RoHS 3 and REACH, ensuring safety and environmental standards for international supply chains.
• Versatile right-hand thread design compatible with standard UNC 6-32 nuts and components for broad industrial application.

Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to address critical alignment and wear issues in precision assemblies. The 18-8 stainless steel material combined with a passivated finish provides excellent resistance to oxidation and chemical exposure, making it ideal for machinery, automotive, and electronic enclosures operating in corrosive or high-moisture environments. The 3/4" shoulder length with precise tolerances acts as a reliable pivot or spacer, minimizing misalignment in rotating parts such as gears, pulleys, and linkages. Its hex socket head allows for secure fastening in tight spaces, while the Class 2A thread fit ensures consistent performance in high-vibration applications, reducing maintenance downtime and improving operational reliability.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder diameter is 5/32" with a tolerance of -0.001" to 0", and the shoulder length is 3/4" with a tolerance of 0" to 0.002" for precise assembly. It is manufactured from 18-8 stainless steel with a passivated finish, achieving a hardness of Rockwell B55 and tensile strength of 70,000 psi. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
