S-96655A131 10-32 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 diameter with tight tolerance control
• High-strength performance delivering 70,000 psi tensile strength and Rockwell B55 hardness for demanding applications
• Secure and efficient installation with knurled hex socket head design preventing tool slippage
• Reliable thread engagement through Class 2B UNF fine threads for vibration resistance
• Versatile partial threading allowing unthreaded shoulder sections to act as pivots or spacers
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global market use

Professional Applications & Engineering Value

This 10-32 UNF shoulder screw addresses critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery exposed to moisture or chemicals, while the 1/2" shoulder diameter with controlled tolerances ensures precise bearing surfaces for rotating components. The partially threaded design allows the unthreaded shoulder section to serve as a pivot point in linkages, guides in linear motion systems, or spacers in electronic enclosures. The knurled hex socket head combined with Class 2B thread fit delivers secure installation without cam-out, maintaining clamping force in high-vibration environments like automotive fixtures, packaging equipment, and industrial robotics.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit for UNF fine threads, shoulder diameter tolerance of -0.004" to -0.002", and shoulder length tolerance of -0.005" to 0.005". Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for international industrial markets and electronic applications requiring restricted substance control.
