• High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength for demanding applications
• Secure, non-slip installation provided by the knurled socket head and hex drive for reliable torque transfer
• Consistent thread engagement due to Class 2A thread fit and coarse UNC thread for faster assembly
• Excellent durability from Rockwell B55 hardness, maintaining integrity under repeated use
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to solve critical alignment and durability challenges in industrial assemblies. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive, and electronic equipment exposed to moisture or chemicals. The 3/16" shoulder length with precise tolerances provides a stable bearing surface, preventing component misalignment and reducing wear in pivoting or rotating mechanisms. The knurled socket head enhances grip during installation, minimizing tool slippage in high-torque scenarios. With a coarse thread and Class 2A fit, it ensures quick, reliable fastening in right-hand thread applications, streamlining production and maintenance processes while upholding structural integrity under loads up to 70,000 psi tensile strength.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. Shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005". It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory acceptance in global markets.
