    Hex Nuts

    The most commonly used hex nuts, these are suitable for fastening most machinery and equipment.
    Low-Strength Steel
    Rated Grade 2, Class 6, or lower, these nuts are about half as strong as medium-strength nuts. They are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.
    Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

    Corrosion-Resistant Stainless Steel
    18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
    Seize-Resistant Nitronic 60 Stainless Steel—With an inherently slippery surface, these nuts are less likely than 410 stainless steel nuts to stick and bind as you install them. Since they don't need coating or lubricant, they're often used in particle-free environments. They also stand up to salt water and mild chemicals, such as cleaners and degreasers.

    Narrow-Profile Hex Nuts

    Image of Product. Bottom orientation. Hex Nuts. 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.
    Corrosion-Resistant Stainless Steel
    18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
    Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these nuts have a dark, matte coating to create a finished look. They resist rust in wet and outdoor environments, but won't hold up to the harsh chemicals that 316 stainless steel can.
