USA 2H Heavy Hex Nut, A194 / Sa 194, Plain (Inch)
USA-made 2H Heavy Hex Nuts A194 / SA 194 Plain are high-strength fasteners manufactured in compliance with ASTM A194 / ASME SA 194 Grade 2H specifications. These heavy hex nuts feature a larger wrenching surface and thicker profile for enhanced load distribution and superior strength. The plain (uncoated) finish provides a natural steel surface, ideal for applications where post-finishing or coating will be applied, or for controlled indoor environments.
Proudly made in the USA, these A194 / SA 194 Grade 2H Heavy Hex Nuts are heat-treated and precision-machined to meet strict mechanical property requirements. Designed for use in high-pressure and high-temperature service, they are commonly used with studs and bolts in flanges, valves, pressure vessels, and other critical assemblies in oil, gas, and power generation industries.
