Professional Applications & Engineering Value
This alloy steel set screw is engineered to solve critical challenges in industrial machinery, automotive, and heavy equipment applications where vibration resistance and secure positioning are paramount. The headless design with a 5/8" hex drive allows for flush mounting in confined spaces, while the cup point aggressively grips shafts and collars to prevent rotational slip. Made from high-strength alloy steel and heat-treated to Rockwell C45 hardness, it withstands repetitive stress and harsh environments. The 1 1/4"-7 UNC coarse thread ensures rapid installation and robust holding in industrial set screw uses, reducing maintenance downtime and enhancing assembly reliability.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for tight dimensional accuracy and superior thread engagement. It conforms to ASME B18.3 and ASTM F912 specifications, ensuring consistent manufacturing quality. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable industrial practices.
