Professional Applications & Engineering Value
This 1/4"-20 x 4 3/4" hex head screw is engineered for industrial applications where strength and corrosion resistance are critical. Made from 18-8 stainless steel, it withstands moisture, chemicals, and temperature variations, preventing failure in machinery, construction, and marine settings. The UNC coarse thread and Class 2A fit provide quick, reliable engagement, reducing the risk of cross-threading in high-vibration environments. With an external hex drive and fully threaded shank, it ensures uniform clamping force, making it ideal for heavy-duty fastening in structural assemblies, equipment frames, and automotive components, where consistent performance under 80,000 psi tensile strength is essential.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a Class 2A thread fit for precise dimensional accuracy and interchangeability. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufacturing conforms to industry norms for inch-system measurements, including a coarse thread spacing and right-hand thread direction, supporting reliable use in regulated sectors.
