Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
- Superior torque transmission and slip resistance thanks to the external square drive and square head design, preventing tool cam-out during installation.
- Reliable and secure fastening with the cup tip design that bites into the shaft material, providing excellent vibration resistance and holding power.
- Optimized for quick assembly with coarse UNC threads and Class 2A thread fit, ensuring easy starting and consistent engagement.
- Enhanced durability and wear resistance from a Rockwell B80 hardness, maintaining thread integrity and performance under repeated use.
- Guaranteed dimensional consistency and interchangeability by conforming to the rigorous ASME B18.6.2 standard.
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.
Professional Applications & Engineering Value
This 5/16"-18 UNC Square Head Set Screw is engineered to solve critical challenges in power transmission and motion control systems. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for food processing, marine, and chemical applications where moisture is a concern. The coarse thread spacing and Class 2A thread fit offer fast installation and reliable performance in materials where fine threads might strip. The combination of the square head for high-torque application and the cup tip design ensures maximum grip on shafts, pulleys, and gears, preventing axial movement and component slippage even under high vibrational loads. This makes it an indispensable component for securing collars, bearings, and handles in heavy machinery and industrial equipment.
Specification Summary & Compliance
This set screw features a 5/16"-18 UNC thread with a Class 2A thread fit for consistent dimensional accuracy and assembly. It is manufactured in compliance with the ASME B18.6.2 standard, ensuring mechanical properties and interchangeability. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental regulations for hazardous substances.
