ASTM A453 GR 660 CLASS D Heavy Hex Nuts

What Are ASTM A453 GR 660 Class D Heavy Hex Nuts?

ASTM A453 GR 660 Class D Heavy Hex Nuts are fasteners that meet the ASTM A453 specification. The specification covers a range of grades from Grade 660A up to Grade 660D. Grade 660A is the lowest grade available while Grade 660D is the highest grade available. The higher the grade, the higher the temperature resistance of the nut and its ability to withstand wear and tear over time.

These ASTM A453 GR 660 Class D Heavy Hex Nuts are commonly used in industries such as oil and gas production, chemical processing, power generation, and aerospace engineering because they can handle higher temperatures without losing strength or becoming brittle. They also provide superior corrosion resistance when exposed to harsh chemicals or acidic environments. Additionally,  ASTM A 453 Grade 660 Class D Heavy Hex Nut are ideal for applications that require frequent disassembly and reassembly as they allow for easy installation and removal with minimal torque requirements. We offer various kinds of products like Copper Bolts, Copper Nuts, etc.

The primary benefit of using these nuts is their superior performance in high-temperature applications due to their strong metallurgical properties which include excellent corrosion resistance and fatigue strength even at elevated temperatures up to 1000°F (537°C).

Types of ASTM A453 GR 660 Class D Heavy Hex Nuts

ASTM A453 GR660 Class D heavy hex nuts come in several different sizes ranging from 0-4 inches (0-101 mm). They also come in various thread pitches including UNC (Unified National Coarse), UNF (Unified National Fine), 8UN (8 threads per inch), 16UN (16 threads per inch), 12UN (12 threads per inch), 24UN (24 threads per inch), 32UN (32 threads per inch). Additionally, these ASTM A453 Gr.660 Heavy Hex Nuts can be customized to meet specific requirements including special shapes and sizes as well as non-standard materials such as stainless steel or aluminum alloys.
