Featured Heavy Hex Nuts:
ASTM A194 Grade 2H Heavy Hex Nut
The ASTM A194 Grade 2H Heavy Hex Nut is widely considered the workhorse of the industrial fastener world. Designed to be used with class 2A studs or bolts in high-pressure/high-temperature applications, the 2H Heavy Hex Nut represents an economical solution where strength and cost are paramount. The Heavy Hex Nut is made of carbon alloy with a class2B fit. The high carbon content of the Heavy Hex Nut provides for additional strength. While the product is not particularly corrosion resistant, the Heavy Hex Nut may be plated for additional protection against weathering and dilation. The mechanical properties of the 2H Heavy Hex Nut are essentially identical to the DH nut, allowing their direct substitution for each other.
 ASTM 453 Grade 660B Heavy Hex Nut
The ASTM 453 Grade 660B Heavy Hex Nut is an ideal solution for extreme service where material creep, sustained corrosion resistance, and strength are imperative. The 660B Heavy Hex Nut is made of premium austenitic steel and precipitation-hardened. The 660B Heavy Hex Nut is an industry favorite for applications in extreme conditions such as those encountered in oceaneering.
