• High-strength durability with 70,000 psi tensile strength and 35,000 psi shear strength for heavy-duty applications.
• Secure and easy installation using the 3/32" hex socket drive and knurled head for improved grip.
• Reliable thread engagement with Class 2A UNC coarse threads for quick assembly and vibration resistance.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.
• Consistent hardness at Rockwell B55 for long-lasting wear and deformation resistance.

Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw is engineered to address common industrial challenges such as misalignment and component wear. The 1" shoulder length provides a precise pivot point or bearing surface, reducing friction and extending the life of moving parts in machinery. With a 10-24 UNC coarse thread and hex socket head, it offers quick, secure fastening in assemblies requiring repeated adjustments, such as in conveyor systems, robotics, and automotive fixtures. The knurled head texture enhances handling during installation, while the material's inherent corrosion resistance ensures reliability in moist or chemical-exposed environments, making it a versatile choice for precision engineering applications.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit for standard tolerance and features a shoulder diameter of 3/16" with tolerances from -0.004" to -0.002" and shoulder length of 1" with tolerances from -0.005" to 0.005". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for industrial use.
