- High mechanical strength with a Rockwell C45 hardness, ensuring long-term reliability under heavy loads.
- Easy installation and removal using a standard 1/4" hex key, simplifying maintenance.
- Broad industrial compatibility with the 1/2"-13 UNC coarse thread, ideal for a wide range of machinery and equipment.
- Compliance with major industry standards including ASME B18.3, ensuring quality and safety.
Professional Applications & Engineering Value
This 1/2"-13 UNC set screw is engineered to solve critical fastening challenges in heavy-duty industrial applications. Constructed from Black Oxide Alloy Steel, it offers excellent resistance to wear and environmental factors, extending service life in harsh conditions. The extended tip and Class 3A thread fit provide a deeper, more secure engagement with components, effectively preventing loosening due to vibration—a common issue in machinery and automotive assemblies. Its coarse thread and right-hand direction ensure quick installation and reliable performance, making it a go-to solution for engineers requiring robust, headless fasteners that maintain alignment and space efficiency.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 3A thread fit for superior tolerance control and a 1/2"-13 UNC coarse thread per ASME specifications. The extended tip features a length of 0.26" with tight tolerances (e.g., tip diameter: 0.343" with -0.009" to 0 tolerance). It is manufactured in compliance with ASME B18.3 and meets environmental regulations such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for global industrial use.
