Professional Applications & Engineering Value

This socket head cap nut delivers critical engineering advantages in demanding industrial environments where space constraints and vibration resistance are paramount. The alloy steel construction provides exceptional tensile strength for heavy machinery, automotive assemblies, and precision equipment applications. The partially threaded design optimizes the strength-to-weight ratio while maintaining full Class 2B thread engagement for secure fastening. The coarse UNC threading (5/8"-11) ensures rapid installation and superior resistance to loosening under dynamic loads. With its hex drive configuration and precise 1.028" hole diameter compatibility, this nut solves accessibility challenges in tightly spaced assemblies while delivering consistent clamping force across industrial socket nut applications requiring reliable, long-term performance.

Specification Summary & Compliance

Manufactured to precise dimensional standards including 0.98" OD, 1" height, and 1/2" thread depth with Class 2B thread fit tolerance for optimal engagement. Thread specifications conform to 5/8"-11 UNC coarse thread standards with right-hand direction. Compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directive with exemption 6(a) for lead as an alloying element in steel, ensuring environmental responsibility in industrial supply chains.
