Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance in industrial applications where vibration resistance and corrosion protection are paramount. The Class 3A thread fit provides superior dimensional accuracy that prevents loosening in high-vibration machinery, while the UNC coarse threading enables rapid installation in production environments. The 90° cone point creates positive mechanical locking by concentrating pressure on a small surface area, ideal for securing gears, pulleys, and collars on rotating shafts. With Rockwell C45 hardness, this hex headless set screw maintains its structural integrity under repeated stress cycles, making it particularly valuable in automotive, manufacturing, and heavy equipment applications where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 standards with Class 3A thread fit precision for superior dimensional control. Features 3/8"-16 UNC coarse threads with right-hand direction and 1-1/4" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
