Professional Applications & Engineering Value
This 12-point flange screw delivers exceptional engineering value in heavy machinery, structural steel connections, and high-vibration environments where reliability is critical. The alloy steel construction with Rockwell C37 hardness provides superior resistance to shear forces and environmental degradation. The 3/4"-10 UNC coarse thread with Class 3A thread fit ensures rapid installation and secure fastening in thick materials, while the integrated flange design distributes clamping force effectively, preventing surface damage and maintaining joint integrity. The external 12-point drive accommodates high torque applications common in industrial maintenance and construction, making it ideal for critical connections in manufacturing equipment, structural frameworks, and heavy vehicle assemblies where failure is not an option.
Specification Summary & Compliance
This 3/4"-10 UNC flange screw features Class 3A thread fit precision with coarse thread spacing and partial threading over a 2" minimum thread length. Manufactured to IFI 115 specifications with dimensional accuracy including 3/4" head height and width, 1 1/8" flange diameter, and 3" overall length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe industrial use worldwide.
