Key Features & Benefits at a Glance
- Superior vibration resistance with nylon patch thread locker that maintains locking integrity up to 250°F, preventing loosening in high-stress environments.
- Exceptional holding power due to Class 3A external thread fit and coarse UNC thread, ensuring precise, secure fastening in industrial assemblies.
- High durability and wear resistance from alloy steel construction and Rockwell C45 hardness, providing long-term reliability under heavy loads.
- Easy installation and removal with 5/32" hex drive and headless design, allowing flush mounting and access in confined spaces.
- Enhanced grip and alignment thanks to the extended tip design, improving contact and reducing component slippage.
- Broad industrial compliance meeting ASME B18.3 standards, RoHS 3, and REACH, ensuring safety and environmental responsibility.
- Optimized for coarse thread applications with 5/16"-18 UNC size, ideal for quick assembly and disassembly in machinery and equipment.
Professional Applications & Engineering Value
This 5/16"-18 UNC set screw is engineered to address common industrial challenges like vibration-induced loosening and misalignment in heavy machinery, automotive systems, and precision equipment. The alloy steel material, combined with Rockwell C45 hardness, ensures high tensile strength and resistance to deformation under dynamic loads. The nylon patch thread locker effectively dampens vibrations, maintaining clamp load without compromising performance up to 250°F. Its coarse thread and Class 3A external thread fit provide tight tolerances for reliable engagement in industrial applications, while the extended tip improves positioning in shafts and collars. This design minimizes maintenance downtime and enhances operational safety in demanding environments.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including Class 3A external thread fit for superior tolerance and UNC coarse threads with 5/16"-18 size. It meets ASME B18.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for global industrial use.
