Product Description

Gr 8.8 Aalloy steel Black ASTM A194-2H Hex Nuts


Heavy Hex Nuts are a favorite in the fastener industry. These six-sided, internally-threaded Heavy Hex Nuts are one of the strongest, most durable fasteners in the industry, designed to sustain the strains of the most extreme industrial conditions. Permanent Technologies provides Heavy Hex Nuts in various grades, finishes, threads, and sizes, as well as custom orders to fit your unique industrial need. ASTM A194 is a standard specification for carbon and alloy steel nuts used in high-pressure and high-temperature service. The "2H" designation specifies a particular grade of heavy hex nuts with higher strength and temperature resistance. These hex nuts are used in critical applications, often in conjunction with ASTM A193 alloy steel bolts, where high strength and durability are essential, such as in pressure vessels, flanges, and piping systems in industries like petrochemical, oil and gas, and power generation.
