S-91410A766 7/16"-14 x 1 1/2" ASME B18.6.2 Set Screws

Key Features & Benefits at a Glance

• Superior vibration resistance from the cup point tip design that bites into surfaces for reliable, long-term holding power
• High-strength steel construction with Rockwell B80 hardness ensures exceptional durability and resistance to wear in demanding applications
• Precise Class 2A thread fit provides smooth assembly and consistent clamping force with reduced risk of cross-threading
• Coarse UNC threads enable faster installation and are less prone to clogging with debris in industrial environments
• External square drive head allows for high-torque application with standard tools, preventing cam-out and ensuring secure fastening
• Full compliance with ASME B18.6.2 standards guarantees dimensional accuracy and reliable performance in mechanical assemblies
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance for use in regulated industries worldwide

Professional Applications & Engineering Value

This 7/16"-14 UNC steel set screw delivers critical engineering solutions where vibration resistance and positional security are paramount. The cup point tip creates permanent dimples in shaft surfaces, preventing axial movement in pulleys, gears, and collars even under continuous operational stress. Manufactured from high-strength steel with Rockwell B80 hardness, it maintains structural integrity in heavy machinery, automotive components, and power transmission systems. The coarse thread design ensures reliable performance in environments where fine debris accumulation might compromise thread engagement. With its external square drive accommodating high torque values, this fastener addresses the common industrial challenge of securely locking rotating components while withstanding dynamic loads and vibration-induced loosening.

Specification Summary & Compliance

This set screw features 7/16"-14 UNC coarse threads with Class 2A thread fit per ASME standards, ensuring precise dimensional tolerances for consistent performance. The fastener is manufactured in compliance with ASME B18.6.2 specifications governing dimensional requirements and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for global industrial applications.
