Professional Applications & Engineering Value
This 3/8"-16 UNC set screw delivers critical engineering solutions for industrial applications requiring permanent shaft positioning and component security. The zinc plated alloy steel construction combined with Rockwell C45 hardness ensures reliable performance in high-stress environments where vibration resistance is paramount. The hex headless design with cup point provides deep penetration into mating surfaces, preventing rotational slippage in pulleys, gears, and collars. Engineered with Class 3A thread fit and coarse thread spacing, this right-hand thread fastener maintains precise alignment while accommodating manufacturing tolerances. Ideal for machinery assembly, automotive components, and industrial equipment where maximum holding power and space constraints are significant considerations.
Specification Summary & Compliance
This set screw features 3/8"-16 UNC coarse threads with Class 3A thread fit for precision engagement. Manufactured to meet ASME B18.3 specifications (ASTM F912) with Rockwell C45 hardness rating. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications. The zinc plated surface treatment provides corrosion resistance while maintaining dimensional accuracy per specified standards.
