• Easy installation and removal using the hex socket drive and knurled head, allowing for high torque application without slippage.
• Consistent quality and compliance meeting RoHS 3 and REACH standards, ensuring safety and environmental responsibility.
• Durable and wear-resistant with Rockwell B55 hardness, maintaining integrity under repeated stress and load.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address common industrial challenges such as misalignment, component wear, and fastener failure in high-stress environments. The 18-8 Stainless Steel material provides excellent corrosion resistance, making it suitable for machinery, automotive, and outdoor equipment where exposure to moisture and chemicals is a concern. The 3/16" thread length and 1/2" shoulder length ensure precise positioning and reduced friction in rotating parts like bearings, pulleys, and linkages. With a hex socket drive and knurled head, it allows for secure tool engagement, minimizing installation errors and enhancing operational efficiency in assembly lines and maintenance tasks.

Specification Summary & Compliance

The screw features Class 2A thread fit for standard UNC coarse threading, ensuring reliable engagement and interchangeability. Shoulder diameter and length tolerances are tightly controlled (-0.004" to -0.002" for diameter and -0.005" to 0.005" for length) to maintain precision in mounting applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial use.
