- High tensile strength of 70,000 psi ensures reliable performance under heavy mechanical stress and vibration.
- Effortless installation and removal with the No. 2 Phillips drive, minimizing slippage and tool wear.
- Precise and secure fastening achieved through Class 2A UNC coarse threads, providing excellent grip in various materials.
- Full threading along the 1/2" length allows for maximum engagement and adjustability in assembly applications.
- Compliance with major industry standards including ASME B18.6.3, ensuring consistent quality and interchangeability.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 8-32 truss head screws combine Black-Oxide 18-8 Stainless Steel with a robust Phillips drive to address common fastening challenges. The rounded truss head offers a low-profile, wide bearing surface that distributes clamp load effectively, reducing the risk of surface indentation on softer materials. With coarse UNC threads and a Class 2A thread fit, they ensure quick assembly and reliable hold in metal, plastic, or wood components, making them ideal for electrical enclosures, machinery panels, and automotive assemblies. The corrosion-resistant finish and high tensile strength provide long-term durability, minimizing maintenance needs in harsh operating conditions.
Specification Summary & Compliance
This screw features a 1/2" length with fully threaded #8-32 UNC coarse threads and a Class 2A thread fit for standard tolerance applications. It is manufactured in accordance with ASME B18.6.3 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in industrial use.
