S-90292A042 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance and strength from 17-4 PH Stainless Steel, ideal for harsh industrial environments.
• Precise alignment and secure component positioning with a standard shoulder diameter of 5/32" and controlled tolerances.
• High-reliability thread engagement thanks to the 6-32 UNC coarse threads with a Class 3A fit, reducing cross-threading risks.
• Superior load-bearing capability with a tensile strength of 130,000 psi and minimum shear strength of 65,000 psi for demanding applications.
• Secure, non-slip fastening enabled by the knurled socket head and 3/32" hex drive, allowing for high torque application.
• Consistent performance and durability ensured by Rockwell C28 hardness, maintaining integrity under repeated use.
• Global compliance and environmental safety by meeting RoHS 3 and REACH regulations, ensuring unrestricted use in regulated markets.

Professional Applications & Engineering Value

This 17-4 PH Stainless Steel shoulder screw is engineered to solve critical alignment and strength challenges in precision assemblies. Its 6-32 UNC coarse thread and Class 3A fit provide reliable, vibration-resistant fastening in machinery, automotive, and aerospace components, where misalignment can cause equipment failure. The knurled socket head with a 3/32" hex drive ensures secure tool engagement, preventing stripping during high-torque installation. The standard shoulder acts as a precise pivot or spacer, maintaining exact part positioning in rotating assemblies like gears and pulleys. Made from high-strength stainless steel, it resists corrosion and maintains 130,000 psi tensile strength under extreme operational stress, reducing maintenance needs and downtime in industrial settings.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precision tolerance. Key dimensional specifications include a thread diameter of 0.138", shoulder diameter of 5/32" (tolerance: -0.004" to -0.002"), and shoulder length of 5/16" (tolerance: -0.005" to 0.005"). The manufacturing ensures consistent Rockwell C28 hardness and mechanical properties, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial use without hazardous substance restrictions.
