Professional Applications & Engineering Value

This 316 Stainless Steel Shoulder Screw is engineered to address critical challenges in precision assemblies. The Class 3A thread fit and UNC coarse thread provide superior holding power and resistance to loosening in vibrating machinery, making it ideal for robotics, automotive fixturing, and conveyor systems. The knurled socket head with a 3/32" hex drive ensures tool engagement remains secure during high-torque installation, reducing the risk of head stripping. Its high tensile strength and corrosion-resistant material make it suitable for washdown environments, chemical processing equipment, and marine applications, where durability and reliability are non-negotiable. By integrating precision dimensions with industrial-grade materials, this shoulder screw minimizes downtime and maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with an 8-32 thread size and Class 3A fit for precise thread engagement. Shoulder diameter and length are manufactured to tight tolerances (e.g., shoulder diameter: -0.004" to -0.002") to ensure consistent performance in jigs, pivots, and spacers. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated industrial and electronic assemblies without hazardous substances.
