Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 316 stainless steel socket head cap screw delivers exceptional performance where corrosion resistance and strength are critical. The passivated finish significantly enhances corrosion protection, making it suitable for chemical processing, marine equipment, and food processing machinery where exposure to moisture and aggressive substances is common. The 5/8"-11 UNC coarse thread provides rapid assembly and superior holding power in softer materials or where vibration resistance is essential. With its 1/2" hex drive and socket head design, this fastener enables high-torque installation in space-constrained applications, from heavy machinery to structural frameworks, ensuring reliable long-term performance where failure is not an option.

Specification Summary & Compliance

This socket head cap screw features Class 3A thread fit for precision assembly with consistent engagement. Manufactured to UNC coarse thread standards with 5/8"-11 threading and partial threading configuration. The fastener maintains dimensional accuracy with specified head diameter (15/16"), head height (5/8"), and overall length (5 1/2"). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
