Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in industrial applications where vibration resistance and permanent positioning are critical. The headless design with hex drive provides flush mounting in confined spaces while maintaining high torque capability. The UNC coarse thread configuration ensures rapid installation in production environments, while the ball tip creates concentrated contact pressure that minimizes shaft damage during securement. Engineered with Rockwell C32 hardness throughout and Rockwell C60 hardened tip, this set screw maintains its mechanical properties under heavy loads, making it ideal for power transmission components, machinery assemblies, and permanent fastening applications where reliability cannot be compromised.
Specification Summary & Compliance
This 1/2"-13 UNC set screw features Class 2A thread fit for consistent dimensional accuracy and proper clearance in industrial applications. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental responsibility in global supply chains. With 1-1/2" length and 0.5" thread diameter, this fastener maintains precise coarse thread spacing according to UNC specifications for reliable performance in various engineering applications.
