Professional Applications & Engineering Value

Engineered for demanding industrial applications, these Grade 8 hex head screws deliver exceptional performance where failure is not an option. The black phosphate steel construction provides superior corrosion protection in harsh environments, while the UNF fine thread configuration ensures precise fit and superior vibration resistance compared to coarse thread alternatives. The integrated flange design eliminates the need for separate washers, distributing clamp load over a wider area to prevent surface damage and maintain joint integrity. With 150,000 PSI tensile strength and Rockwell C32 hardness, these fully threaded fasteners are ideal for heavy machinery, structural assemblies, and automotive applications where reliability under extreme conditions is paramount.

Specification Summary & Compliance

This 1/2"-20 UNF fine thread fastener features Class 2A thread fit tolerance for precise engagement and meets IFI 111 specifications where identified as SAE J429. The product maintains compliance with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards, ensuring environmental responsibility and workplace safety. Manufactured to Grade 8 strength classification with consistent Rockwell C32 hardness, these screws deliver reliable performance across industrial applications requiring inch system measurements and external hex drive compatibility.
