Choose a hex nut with the right profile, material, and strength for your application.
Heavy-Profile Hex Nuts for High-Pressure Applications
These nuts are hardened, so they maintain their strength under high pressure and temperature. Pair them with ASTM A193 screws to fasten critical components, such as valves and flanges, in pressure tanks, boilers, and heat exchangers. About 10% wider and taller than standard-profile hex nuts, these handle heavier loads by distributing them over a larger area.
