Professional Applications & Engineering Value

This black-oxide alloy steel socket head cap screw delivers critical engineering advantages for industrial applications where surface protection and high-strength fastening are paramount. The nonmarring brass tip specifically addresses the common challenge of damaging finished surfaces during assembly, making it ideal for precision machinery, automotive components, and electronic enclosures where cosmetic integrity matters. The 3/8"-16 UNC Class 3A threads provide superior engagement in coarse thread applications, resisting loosening under vibration while the 180,000 psi tensile strength ensures structural integrity in heavy-duty fastening scenarios. The combination of Rockwell C39 hardness and fully threaded design offers consistent performance across the entire fastener length, making it particularly valuable for applications requiring uniform clamping force and reliable hex drive installation in confined spaces.

Specification Summary & Compliance

This socket head cap screw features precision 3/8"-16 UNC Class 3A threads with right-hand orientation and coarse thread spacing, manufactured to exacting dimensional standards. The fastener complies with ASME B18.3 specifications and ASTM A574 material standards, ensuring consistent quality and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) adherence, confirming the product meets current regulatory requirements for hazardous substance restrictions. The inch system measurements guarantee proper fitment and interchangeability with standard components across industrial applications.
