Professional Applications & Engineering Value
This 5-40 UNC set screw delivers critical holding power in precision machinery, automotive systems, and electronic enclosures where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel material combats rust in humid or chemical-exposed environments, while the Class 3A thread fit ensures tight tolerances that prevent loosening under dynamic loads. Its headless design and 1/16" hex drive allow flush mounting in space-constrained applications, and the extended tip bites securely into shafts or collars to maintain alignment. Engineered to ASME B18.3 specifications, it provides consistent performance for OEMs and maintenance teams requiring reliable set screws with documented compliance.
Specification Summary & Compliance
This set screw features a 5-40 UNC coarse thread with Class 3A thread fit for precision assembly, manufactured from 18-8 stainless steel with Rockwell B80 hardness. Dimensions include 3/8" length, 1/16" hex drive, and extended tip (0.083" diameter, 0.033" length). The product conforms to ASME B18.3 mechanical standards and is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental and safety regulations are met for industrial use.
