Commonly used in valves, pumps, and shafts, these 400 nickel nuts resist salt water and caustic chemicals.

These metric nuts have a high strength-to-weight ratio and resist acids and salt water.

Choose these nuts for their adherence to strict military standards for material and construction.

Also known as small-pattern hex nuts, these are about 20% narrower than standard hex nuts for use in tight spaces where standard hex nuts won't fit.

Made with fine-pitch threads, vibration is less likely to loosen these metric nuts than those with coarse-pitch threads since the threads sit closer together. Also called jam nuts, they are roughly half the height of standard hex nuts, so they’re good for applications with low clearance.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion.

With threads that tighten to the left and made of 316 stainless steel, these nuts won’t loosen from counterclockwise motion in saltwater and corrosive environments. They’re half the height of standard hex nuts, so they fit where there’s low clearance.

These metric nuts are made of 316 stainless steel and half as tall as regular hex nuts—use them around chemicals and salt water when space is limited.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 5 steel, so you can used these inch-sized nuts for most fastening applications.

These nuts are half the height of standard hex nuts, and have closely spaced threads to prevent loosening from vibration. Half as strong as medium-strength steel nuts, they are often used for light-duty applications, such as fastening signs in place.

These nuts should be used for light duty fastening applications, such as securing access panels.

These nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.

Bronze nuts are stronger and more resistant to salt water than brass nuts.

Made from brass, these metric nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. About half the height of standard hex nuts, they are useful in low-clearance applications but have less tensile strength.

These nuts tighten to the left and won’t loosen from counterclockwise motion.
