Professional Applications & Engineering Value

This 18-8 stainless steel hex socket set screw delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The headless design allows flush mounting in pulleys, gears, and collars, while the 90° cone point creates permanent positioning by concentrating pressure on a small contact area. Its Class 3A thread fit with UNC coarse threading ensures rapid assembly and superior clamping force in high-stress applications across machinery, automotive, and manufacturing sectors. The combination of Rockwell B80 hardness and 1/4" hex drive provides optimal torque transmission without stripping, making it ideal for permanent installations requiring reliable set screw performance.

Specification Summary & Compliance

This 1/2"-13 UNC set screw features precise Class 3A thread fit tolerances with coarse thread spacing for industrial applications. Manufactured to ASME B18.3 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 1-1/4" length and right-hand thread direction provide standardized installation across compatible components.
