- High mechanical strength and durability from Rockwell B80 hardness, resisting wear and deformation under load.
- Easy installation and removal with a 5/32" hex drive, allowing for efficient assembly and maintenance with standard tools.
- Reliable performance in high-vibration applications due to coarse UNC threads and flat tip design, maintaining position securely.
- Compliance with industry standards including ASME B18.3, ensuring consistent quality and interchangeability.
- Environmentally safe usage with RoHS 3 and REACH compliance, meeting global regulatory requirements for hazardous substances.
Professional Applications & Engineering Value
This 18-8 stainless steel set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. Its headless design and hex drive enable flush mounting in tight spaces, while the UNC coarse threads and Class 3A fit provide superior grip in high-vibration settings like machinery, automotive assemblies, and electrical enclosures. The Rockwell B80 hardness ensures the screw withstands repetitive stresses without stripping, making it a reliable choice for permanent or adjustable positioning in demanding industrial applications. Combined with corrosion-resistant properties, it reduces maintenance needs and extends service life in humid or chemical-exposed environments.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Thread Fit of Class 3A for tight tolerances and UNC coarse thread spacing with a size of 5/16"-18. It meets ASME B18.3 specifications for consistency and performance. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and safe for various industrial and international uses.
