S-97345A116 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and chemical exposure.
• Exceptional mechanical strength offering 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable, high-stress applications.
• Precise thread engagement with Class 3A fit and 6-32 UNC coarse thread, ensuring secure fastening and vibration resistance.
• Enhanced grip and easy installation from the knurled socket head and 3/32" hex drive, reducing slippage during assembly.
• Accurate component alignment with a 7/8" shoulder length and controlled diameter tolerance, providing stable pivoting or spacing.
• Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe, sustainable use in global markets.
• Durable and long-lasting performance due to Rockwell B79 hardness, maintaining integrity under repeated loads.

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address common industrial challenges, such as component misalignment and corrosion-induced failure. The UNC coarse thread and Class 3A fit provide quick, secure fastening in assemblies subject to vibration, while the knurled socket head enhances torque application without tool slippage. Ideal for machinery, automotive, and electronics, the precise shoulder diameter and length ensure accurate alignment in rotating parts or as a spacer, reducing wear and maintenance costs. Its high tensile and shear strength supports heavy-duty applications, and the corrosion-resistant material extends service life in moist or chemical environments, delivering reliable engineering value for B2B procurement.

Specification Summary & Compliance

The screw adheres to UNC thread standards with a Class 3A thread fit for precision, and shoulder dimensions include a diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial use worldwide.
