Professional Applications & Engineering Value

This Grade 5 steel hex nut with 1/4"-20 UNC coarse threading delivers exceptional engineering value for industrial applications where vibration resistance and structural integrity are critical. The extra wide profile significantly increases bearing surface area, effectively distributing clamp load and preventing joint loosening in heavy machinery, construction equipment, and automotive assemblies. Manufactured from medium-carbon steel with proper heat treatment, this fastener maintains its mechanical properties under sustained tension and dynamic loads. The external hex drive configuration allows for high torque application using standard wrenches, while the Class 2B thread fit ensures smooth engagement with mating components. This combination of features makes it ideal for applications requiring repeated disassembly and reassembly without compromising thread integrity.

Specification Summary & Compliance

This hex nut features precision UNC coarse threads with Class 2B tolerance for consistent fit and performance. The manufacturing process adheres to strict quality standards for Grade 5 fasteners, ensuring proper hardness and strength characteristics. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, confirming the absence of restricted substances. Dimensional specifications include 1/4"-20 thread size, 1/2" width across flats, and 15/64" height, providing reliable interchangeability with standard components in inch-based systems.
