Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws deliver critical performance advantages in precision engineering applications where corrosion resistance and high-strength fastening are paramount. The 10-32 UNF fine thread configuration with Class 3A thread fit ensures superior engagement in tapped holes, preventing loosening under vibration while maintaining precise alignment in machinery, automotive, and aerospace assemblies. The combination of 170,000 psi tensile strength and Rockwell C37 hardness provides exceptional durability against shear forces and repeated loading cycles. The hex socket drive enables high-torque installation in confined spaces, making these 3-inch fully threaded screws ideal for critical joints requiring consistent clamping force across the entire fastener length.
Specification Summary & Compliance
Manufactured to ASTM A574 specifications with precision Class 3A thread fit tolerance for superior engagement. Features UNF fine thread spacing with 10-32 thread size and right-hand thread direction. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment on alloy steel provides enhanced corrosion protection while maintaining dimensional stability across the 3-inch length and 5/16-inch head diameter.
