S-97832A390 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
• Superior torque transmission and alignment thanks to the 7/32" shoulder diameter with precise tolerances.
• High-reliability fastening ensured by the Class 3A thread fit for minimal backlash and secure assembly.
• Enhanced grip and reduced tool slippage with the knurled socket head design.
• Robust mechanical performance with 70,000 psi tensile strength and 35,000 psi shear strength for demanding applications.
• Wide compatibility with UNC coarse threads and a standard 3/32" hex drive for common tooling.
• Compliance with global environmental standards including RoHS 3 and REACH for use in regulated industries.

Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw is engineered to provide a dependable pivot, spacer, or axle in precision assemblies. The UNC coarse thread and Class 3A fit ensure fast installation and vibration resistance in machinery, while the knurled socket head prevents cam-out during high-torque applications. Its high tensile and shear strength makes it suitable for automotive, aerospace, and electronics, where components must withstand significant mechanical stress without failure. The corrosion-resistant material and compliant surface treatment guarantee longevity, even in aggressive environments, reducing maintenance needs and total cost of ownership.
