    About Hex Nuts
    industrial info icon

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

    The easiest nuts to twist on and off by hand, these are commonly used to fasten parts that need to be frequently disassembled, such as access panels and covers. The wings give you more leverage than knurled-head nuts, so you can apply greater torque and achieve a tighter fit.

    Image of Product. Front orientation. Square Nuts. Low-Strength Steel Square Nuts.
    Large flat sides make these nuts easy to grip with a wrench and keep them from rotating in channels and square holes. About half the strength of medium-strength steel square nuts, use them in light duty fastening applications, such as securing access panels.
    Black-Zinc-Plated Steel—Black-zinc-plated steel square nuts resist corrosion in wet environments and have a black finish that blends in with dark surfaces.
    Steel—Steel square nuts are best for dry environments, since moisture will cause them to rust.
    Zinc-Plated Steel—Zinc-plated steel square nuts resist corrosion in wet environments.
