    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.

    High-Profile Hex Nuts

    Slightly taller than standard-profile hex nuts, these have a larger gripping area so your wrench or socket won't slip off as you tighten them. They're often used in vehicles and machinery where fasteners can be difficult to reach.

    Narrow-Profile Hex Nuts

    When you have limited space for tightening with a wrench, use these nuts. Since they’re about 20% narrower, they fit in tight spots where standard-profile nuts won't fit. Also known as small-pattern hex nuts.
