Professional Applications & Engineering Value
This high-strength 12-point alloy steel screw addresses critical engineering challenges in heavy machinery, structural assemblies, and industrial equipment where vibration resistance and load integrity are paramount. The 3/4"-10 UNC coarse thread with Class 3A fit ensures precise mating with components while the external 12-point drive provides superior torque transmission without stripping. The integrated flange design distributes clamping force evenly, preventing surface damage and maintaining joint integrity under dynamic loads. With 170,000 psi tensile strength and Rockwell C37 hardness, this fastener withstands extreme mechanical stress in construction, manufacturing, and heavy equipment applications where failure is not an option.
Specification Summary & Compliance
This industrial fastener maintains Class 3A thread fit precision according to UNC standards with 3/4"-10 coarse threading and right-hand orientation. Manufacturing conforms to IFI 115 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The fully threaded design with 2 1/2" length and 1 1/8" flange diameter ensures consistent performance across industrial applications requiring reliable, high-strength fastening solutions.
