Professional Applications & Engineering Value

This 10-24 UNC shoulder screw delivers critical engineering solutions for precision assembly challenges. The alloy steel construction, combined with Rockwell C30 hardness, provides exceptional resistance to shear forces and mechanical wear in automated machinery, robotics, and precision instrument applications. The black oxide finish significantly enhances corrosion resistance, making it ideal for industrial environments where moisture or chemicals are present. The coarse thread spacing and Class 3A thread fit ensure rapid installation with minimal cross-threading risk, while the precisely machined shoulder maintains accurate component positioning and reduces bearing surface wear. These features combine to solve common industrial pain points including misalignment, vibration-induced loosening, and premature fastener failure.

Specification Summary & Compliance

This shoulder screw features Class 3A thread fit with UNC thread form, ensuring precision compatibility with standard mating components. The shoulder diameter maintains tight tolerances of -0.004" to -0.002", while the shoulder length tolerance is held to -0.005" to 0.005" for consistent performance. Manufactured to industry standards with right-hand threads and hex drive configuration. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest international requirements for hazardous substance restrictions.
