S-90337A194 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
• Precise alignment and reduced wear due to the smooth shoulder with tight diameter tolerance (-0.001" to 0") for accurate component positioning
• High-strength performance with 70,000 psi tensile strength and Rockwell B55 hardness, ensuring reliable load-bearing in demanding applications
• Space-saving low-profile socket head allows installation in confined spaces while providing secure hex drive engagement
• Fine thread accuracy with 10-32 UNF Class 2A thread fit ensures vibration resistance and consistent fastening torque
• Environmental compliance with RoHS 3 and REACH regulations, meeting international standards for safe industrial use
• Optimized shoulder length of 5/16" with minimal tolerance (0" to 0.002") for consistent pivot or spacer functionality

Professional Applications & Engineering Value

This 10-32 UNF low profile socket head shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to corrosion and chemical exposure, making it suitable for machinery, automotive, and electronics where environmental factors are a concern. The fine UNF threads and Class 2A fit maintain tight tolerances under vibration, while the smooth, precisely machined shoulder acts as a reliable pivot or bearing surface—reducing wear on mating components. Its low-profile head and hex drive facilitate easy installation in compact designs, ensuring efficient maintenance and long-term performance in automated systems, jigs, and fixtures.

Specification Summary & Compliance
