Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw delivers exceptional engineering value where corrosion resistance and mechanical strength are critical. The passivated finish provides enhanced protection against chemical exposure and saltwater environments, making it ideal for marine equipment, chemical processing plants, and food processing machinery. The Class 3A thread fit ensures precise tolerance control for vibration-resistant assemblies, while the UNC coarse threads facilitate quicker installation in production environments. The hex socket drive allows for high-torque applications in confined spaces, and the partially threaded design provides optimal clamping force distribution. These industrial fasteners solve common challenges of fastener failure in aggressive environments, offering long-term reliability and reduced maintenance costs.

Specification Summary & Compliance

This socket head cap screw features precision 7/16"-14 UNC coarse threads with Class 3A fit for superior thread engagement. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Mechanical properties include 70,000 psi tensile strength and Rockwell B70 hardness, ensuring consistent performance in industrial applications. The 3" length with 1 3/8" minimum thread length provides versatile fastening capabilities while maintaining structural integrity.
