Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance advantages in demanding industrial applications. The extended tip design provides deeper penetration into mating components, creating more secure locking in pulleys, gears, and collars where precise positioning is essential. The Rockwell C45 hardness ensures the square head maintains integrity during high-torque installation, while the coarse UNC 3/8"-16 threading offers superior resistance to vibration-induced loosening in machinery and equipment. The black-oxide surface treatment provides essential corrosion protection in manufacturing environments, making these set screws ideal for automotive assemblies, industrial machinery, and heavy equipment applications requiring durable, reliable fastening solutions.
Specification Summary & Compliance
Manufactured to precise dimensional standards including 1" length with Class 2A thread fit tolerance and extended tip diameter of 0.25" (±0.009"). Fully compliant with ASTM F912 specifications for square head set screws, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) regulations for chemical safety. Right-hand UNC coarse threading ensures compatibility with standard industrial components and applications.
