  • Enhanced thread engagement with 10-32 UNF fine threading and Class 2A fit for secure fastening in delicate mechanisms
  • High-strength performance delivering 40,000 psi tensile strength and Rockwell B55 hardness for demanding applications
  • Easy installation and maintenance with standard hex socket drive requiring only 1/8" Allen wrench access
  • Reliable shear resistance with 22,000 psi minimum shear strength preventing failure under lateral loads
  • Global compliance ready meeting RoHS 3 and REACH regulations for international industrial deployment

Professional Applications & Engineering Value

This precision shoulder screw solves critical alignment challenges in industrial machinery, electrical enclosures, and precision instruments. The 360 brass material provides excellent conductivity and corrosion resistance, while the 5/8" shoulder length acts as precise pivot point or bearing surface. The 10-32 UNF fine thread with Class 2A fit ensures vibration-resistant fastening in thin materials. The hex socket drive allows high-torque installation in confined spaces, making it ideal for assembly line production and maintenance applications requiring repeated disassembly.

Specification Summary & Compliance

Manufactured to exacting standards with Class 2A thread fit and precise shoulder diameter tolerance of -0.002" to 0". Thread specifications conform to UNF standard with 10-32 fine threading and 1/4" thread length. Shoulder dimensions maintain 1/4" diameter with 5/8" length (tolerance 0" to 0.003"). Fully compliant with RoHS 3 (2015/863/EU) under exemption 6(c) and REACH (EC 1907/2006) regulations for industrial use.
