S-97832A353 5-40 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
• Precise component alignment ensured by the 1/2" shoulder length with tight tolerances for stable assemblies.
• High tensile and shear strength (70,000 psi tensile, 35,000 psi min shear) for reliable performance under heavy loads.
• Easy installation and removal with the hex socket drive and knurled head, reducing tool slippage.
• Consistent thread engagement due to Class 3A thread fit and UNC coarse threads for quick assembly.
• Durable and long-lasting with Rockwell B55 hardness, resisting wear in repetitive applications.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.

Professional Applications & Engineering Value

This 5-40 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision machinery, such as in robotics, automotive systems, and electronic enclosures. Made from 18-8 stainless steel, it offers excellent resistance to corrosion and oxidation, reducing maintenance needs in humid or chemical-exposed settings. The 1/2" shoulder length with minimal tolerances provides a stable pivot or spacer, preventing misalignment and wear in moving parts. Combined with a socket head and hex drive, it allows for secure tightening in confined spaces, enhancing assembly efficiency and reliability for B2B industrial applications.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including Class 3A thread fit and UNC thread specifications for consistent performance. Shoulder diameter and length tolerances are tightly controlled (e.g., shoulder diameter: -0.004" to -0.002"). The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use.
