Professional Applications & Engineering Value
This 316 stainless steel headless set screw is engineered to address critical challenges in precision assembly and corrosive environments. Its Class 3A UNF fine threads provide a tighter fit than standard threads, reducing backlash and maintaining clamp force in high-vibration machinery such as motors, pumps, and aerospace components. The headless design with hex drive allows for flush mounting in confined spaces, while the cup point tip bites securely into shafts without causing excessive damage. Manufactured from corrosion-resistant 316 stainless steel, it delivers long-term reliability in marine, chemical processing, and food industry applications where moisture and chemicals are prevalent, ensuring minimal maintenance and reduced downtime.
Specification Summary & Compliance
This set screw features a 1/4"-28 UNF fine thread with Class 3A tolerance for precise fit, a 1/8" hex drive, and 1/4" length. It conforms to ASME B18.3 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global industrial use.
