Professional Applications & Engineering Value
This 1/2"-13 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and vibration-induced loosening. The black-oxide alloy steel construction offers enhanced corrosion resistance, crucial for environments exposed to moisture or chemicals, while the Rockwell C45 hardness ensures the fastener maintains its integrity under high stress. The hex drive and coarse thread spacing facilitate quick, reliable installations in machinery, automotive systems, and heavy equipment, reducing downtime. Its headless design and flat tip provide a flush finish and secure grip, making it ideal for set screw applications in pulleys, gears, and collars where space is limited and precision is paramount.
Specification Summary & Compliance
This set screw features a 1/2"-13 UNC thread with Class 3A fit for precise dimensional accuracy and superior thread engagement. It meets ASME B18.3 specifications for consistent manufacturing quality. Additionally, the product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various industrial and international markets.
