    industrial info icon

    Choose a hex nut with the right profile, material, and strength for your application.

    Hex Nuts

    The most commonly used hex nuts, these are suitable for fastening most machinery and equipment.
    Lightweight Corrosion-Resistant Titanium

    The best of both worlds, these hex nuts are lightweight like aluminum and more corrosion resistant than 316 stainless steel.
    Grade 2 Titanium—Because Grade 2 titanium is 99% pure, it's even more corrosion resistant than other common titanium grades, such as Grades 5 and 9. These nuts are ideal for use in chemical-processing and water-treatment facilities since they stand up to strong acids and other harsh chemicals.
    High-Strength Grade 5 Titanium—More than two times stronger than Grade 2 titanium due to the addition of aluminum and vanadium. These nuts also stand up to salt water, acids, and chemicals but won’t resist harsh chemicals like Grade 2 can.

    Nylon-Insert Locknuts

    Image of Product. Front orientation. Locknuts. Nylon-Insert Locknuts.
    Versatile yet economical, these are the most commonly used locknuts. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.
    High-Strength Lightweight Titanium
    Grade 5 Titanium—The best of both worlds, these locknuts are lightweight like aluminum and as corrosion-resistant as 316 stainless steel. They're ideal for use in chemical-processing and water-treatment facilities since they stand up to strong acids and other harsh chemicals. Grade 5 is the strongest of all the titanium alloys due to its higher aluminum and vanadium content.

    Thin-Profile Hex Nuts

    About half the height of standard-profile nuts, these fit in spaces with low clearance. You can also use them as jam nuts by threading them against another hex nut to hold it in place.
    Lightweight Corrosion-Resistant Titanium
    The best of both worlds, these hex nuts are lightweight like aluminum and more corrosion resistant than 316 stainless steel.
    Grade 2 Titanium—Because Grade 2 titanium is 99% pure, it's even more corrosion resistant than other common titanium grades, such as Grades 5 and 9. These nuts are ideal for use in chemical-processing and water-treatment facilities since they stand up to strong acids and other harsh chemicals.

    Weld Nuts

    Add permanent threads to thin metal with our go-to weld nuts. Unlike press-fit and rivet nuts, these nuts fuse to the base metal, so they won’t twist and pull out. Three evenly spaced projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. All have a collar pilot that guides the nut into the hole, holds it in place while welding, and protects the threads from weld spatter. You can also install them on thick pieces of metal.
    Grade 2 Titanium—The best choice when you need a high strength-to-weight ratio, these nuts are 40% lighter than steel nuts. They’re also our most corrosion-resistant weld nuts, standing up to salt water, strong acids, and other harsh chemicals. Weld them to titanium surfaces.
