Professional Applications & Engineering Value

This 18-8 stainless steel set screw delivers exceptional engineering value in demanding industrial settings where vibration resistance and permanent fastening are critical. The Class 3A thread fit provides superior precision for high-stress applications, while the cup point tip creates permanent dimples in mating surfaces for maximum security against rotational forces. The hex headless design allows for flush mounting in machinery, pulleys, gears, and collars where protruding fastener heads are impractical. Manufactured from corrosion-resistant stainless steel with Rockwell B80 hardness, this set screw maintains integrity in harsh environments including chemical processing, marine applications, and outdoor equipment. The coarse UNC threads ensure quick assembly and disassembly while maintaining holding power in soft materials or where frequent maintenance is required.

Specification Summary & Compliance

This set screw features precision 3/8"-16 UNC coarse threads with Class 3A fit for superior dimensional accuracy and tight tolerances. Manufactured in compliance with ASME B18.3 specifications for socket set screws, ensuring consistent quality and performance. The product meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. Additional specifications include right-hand thread direction, 1/2" length, and serrated locking type for enhanced fastening security in industrial applications.
