Professional Applications & Engineering Value
This 18-8 stainless steel set screw delivers critical performance in demanding industrial applications where vibration resistance and corrosion protection are paramount. The Class 3A thread fit ensures precise engagement with mating components, while the extended tip design provides deeper penetration for superior holding power in shafts, collars, and pulleys. The fine UNF threads (5/16"-24) offer increased tensile strength compared to coarse threads, making these headless set screws ideal for precision machinery, automotive assemblies, and manufacturing equipment where space constraints and reliability are critical factors. The combination of Rockwell B80 hardness and 5/32" hex drive ensures consistent performance in high-torque applications without compromising the drive mechanism.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 standards with Class 3A thread fit precision for superior dimensional accuracy. The extended tip features controlled tolerances (length: -0.005" to 0", diameter: -0.008" to 0") ensuring consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these set screws suitable for global industrial applications requiring strict regulatory adherence.
