Professional Applications & Engineering Value
This 7/16"-14 UNC steel set screw delivers critical engineering solutions for industrial assembly challenges. The coarse thread spacing combined with Class 2A thread fit ensures rapid installation while maintaining vibration resistance in machinery, automotive, and heavy equipment applications. The cup tip design creates concentrated pressure points that securely lock components onto shafts without causing material damage. Manufactured from hardened steel with Rockwell B80 hardness, this fastener maintains its structural integrity under extreme mechanical stress. The external square drive provides superior torque transmission compared to standard hex drives, preventing rounding during high-tension applications. Ideal for permanent positioning of gears, pulleys, and collars in manufacturing environments where reliability is paramount.
Specification Summary & Compliance
This 4" length set screw features precision 7/16"-14 UNC coarse threads with Class 2A thread fit per ASME standards, ensuring dimensional accuracy and interchangeability. The fastener complies with ASME B18.6.2 manufacturing specifications for square head set screws and meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance. The right-hand thread direction and standardized inch measurements provide compatibility with existing industrial equipment and tooling systems.
