Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for permanent component positioning in high-stress applications. The headless hex drive design allows flush mounting in confined spaces while maintaining tool accessibility. With UNC coarse threads and Class 3A precision fit, it eliminates backlash in pulleys, gears, and collars, preventing costly downtime in manufacturing equipment. The 90° cone point tip bites deeply into shaft materials, creating superior resistance against rotational forces in automotive, aerospace, and heavy machinery assemblies. Manufactured to ASME B18.3 specifications, this set screw provides reliable performance where vibration resistance and positional accuracy are paramount.
Specification Summary & Compliance
This 3/8"-16 UNC set screw features precise Class 3A thread fit with coarse thread spacing for optimal engagement. The 7/8" length and 0.375" thread diameter maintain dimensional accuracy per ASME B18.3 standards. Manufacturing complies with ASTM F912 specifications for material consistency and performance. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental regulations for hazardous substance restrictions.
