Professional Applications & Engineering Value
This 316 stainless steel set screw delivers exceptional performance in demanding applications where corrosion resistance and precise component positioning are critical. The Class 3A thread fit provides superior engagement with mating parts, reducing the risk of loosening in high-vibration environments such as machinery, automotive systems, and precision equipment. The cup point design bites firmly into shaft materials, creating permanent alignment without slippage, while the headless configuration enables seamless integration in space-constrained assemblies. With UNF fine threading and 1/4" hex drive, installation torque is efficiently transferred without cam-out, making these fasteners ideal for permanent set applications in pulleys, gears, and collars where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 specifications with Class 3A thread fit for precision UNF fine threading (1/2"-20). Features include 1" length, 0.5" thread diameter, right-hand thread direction, and Rockwell B80 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
