- Easy installation and removal with a square head and external square drive, allowing for high-torque application with standard tools.
- Secure component positioning thanks to the cup tip design, which bites into surfaces to prevent slippage and movement.
- Wide industrial compatibility with a 1"-8 UNC coarse thread, making it suitable for a broad range of machinery and equipment.
- Regulatory peace of mind by meeting ASME B18.6.2 specifications and being RoHS 3 & REACH compliant for global use.
- Optimized for heavy-duty use with a substantial 4" length and 1" head width, ensuring deep engagement and robust performance.
Professional Applications & Engineering Value
This 1"-8 UNC coarse thread steel set screw is engineered to solve critical challenges in industrial assembly, where vibration resistance and secure component locking are paramount. The square head and external square drive enable high-torque installation, reducing the risk of tool slippage and ensuring consistent clamping force in heavy machinery, automotive systems, and construction equipment. Made from hardened steel with a Rockwell B80 rating, it withstands repetitive stress and environmental exposure, while the cup tip digs firmly into shafts or hubs to prevent axial movement. Its Class 2A thread fit and adherence to ASME B18.6.2 standards guarantee precise dimensional accuracy, making it a reliable choice for engineers seeking durability and compliance in set screw applications.
Specification Summary & Compliance
This set screw features a 1"-8 UNC coarse thread with Class 2A fit for standard tolerance and easy assembly. It complies with ASME B18.6.2 manufacturing specifications and is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets environmental and safety regulations for industrial use worldwide.
