Professional Applications & Engineering Value
This 1/4-20 UNC shoulder screw delivers exceptional engineering value in precision assemblies where alignment and durability are critical. The 18-8 stainless steel base material provides excellent corrosion resistance, while the TiCN coating significantly reduces wear in high-cycle applications such as rotating machinery, automation systems, and precision tooling. The precise shoulder diameter of 5/16" with minimal tolerance ensures perfect component positioning, eliminating play and reducing maintenance needs. With its low-profile socket head and 7/16" shoulder length, this fastener solves common challenges in compact designs where space constraints demand reliable, high-strength fastening solutions that withstand continuous operational stress.
Specification Summary & Compliance
This shoulder screw features Class 2A thread fit per UNC standards with precise shoulder dimensions (5/16" diameter, 1/4" length) manufactured to tight tolerances. The component meets Rockwell B55 hardness and 70,000 PSI tensile strength requirements, ensuring mechanical reliability. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making it suitable for global industrial applications requiring environmental responsibility and material safety.
