Professional Applications & Engineering Value

This 3/4"-10 UNC hex nut is engineered for demanding industrial settings where durability and precision are non-negotiable. The black-oxide steel construction offers enhanced corrosion resistance, making it suitable for outdoor machinery, construction equipment, and automotive assemblies exposed to moisture and chemicals. The extra wide profile distributes clamping force more evenly, preventing joint failure in high-vibration environments like heavy machinery and structural frameworks. With its coarse thread design and Class 2B thread fit, it ensures quick, reliable installation without sacrificing strength, reducing downtime in production lines. Ideal for applications requiring ASTM Grade 2H certified fasteners, this nut delivers consistent performance in bolted connections that demand superior load-bearing capacity and long-term reliability.

Specification Summary & Compliance

This hex nut features a 3/4"-10 UNC coarse thread with Class 2B thread fit for precise dimensional accuracy and smooth assembly. It adheres to ASTM A194 specifications for material and manufacturing quality, and meets RoHS 3 (2015/863/EU) compliance under exemption 6(a) for lead as an alloying element in steel. The nut is designed with an external hex drive, a width of 1 1/4", and a height of 47/64", ensuring compatibility with standard tools and components in inch-based systems.
