- Easy and reliable installation with the hex drive design, allowing for high torque application without cam-out.
- Enhanced grip and component alignment from the extended tip, which digs into shafts for superior anti-loosening performance.
- High mechanical strength with a Rockwell B80 hardness, providing excellent durability and resistance to wear.
- Broad industry compatibility through UNC coarse threading, enabling quick assembly and disassembly.
- Guaranteed quality and safety by meeting ASME B18.3 specifications and being RoHS 3 & REACH compliant.
Professional Applications & Engineering Value
This 5/16"-18 UNC Class 3A set screw is engineered to solve critical challenges in industrial assembly, such as component slippage and loosening under dynamic loads. The 18-8 Stainless Steel material offers excellent resistance to rust and corrosion, making it suitable for applications in moist or chemically aggressive environments, including machinery, automotive, and marine equipment. The headless hex drive design allows for flush mounting in tight spaces while the extended tip provides a biting action that securely locks collars, gears, and pulleys onto shafts. Its coarse thread ensures faster installation and higher resistance to vibration, reducing maintenance downtime and improving the reliability of your mechanical systems.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Thread Fit of Class 3A for superior thread engagement and a tip diameter tolerance of -0.008" to 0. It is manufactured in compliance with ASME B18.3 specifications and is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for global industrial use.
