Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.

Twice as strong as low-strength steel screws, these screws are suitable for fastening most machinery and equipment.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water.

Made from 18-8 stainless steel, these set screws have good chemical resistance.

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

Tighten these nuts by turning them to the left; once fastened, they resist loosening from counterclockwise motion.

These nuts have good chemical resistance and may be mildly magnetic.

One-third the weight of steel, these aluminum nuts are corrosion resistant in wet environments and nonmagnetic.

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

Made of 316 stainless steel for excellent corrosion resistance—including in salt water—these nuts tighten to the left and won’t loosen from counterclockwise motion. For use in low-clearance areas, they’re half the height of standard hex nuts.

Made from Grade 5 steel, these inch-sized nuts are suitable for most fastening applications.

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

Also kown as heavy hex nuts, these nuts are about 10% wider and taller than standard hex nuts to distribute load over a large area.

These nuts have good chemical resistance.

More corrosion resistant than 18-8 stainless steel locknuts, these locknuts have excellent resistance to chemicals and salt water.

Includes inch thread sizes. These Grade 8 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low clearance applications or jam one against a hex nut to hold it in place.

Comparable in strength to Grade 8 bolts, these locknuts are about 25% stronger than medium-strength steel locknuts.

Also known as castle nuts, secure these nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance.

About half the strength of medium-strength steel flange locknuts, these are for light duty fastening applications, such as securing access panels.

These coupling nuts have good chemical resistance.

Stainless steel coupling nuts have excellent corrosion resistance in most environments.

These cap nuts have excellent resistance to chemicals and salt water.

About half the strength of medium-strength steel threaded rods, use these for light duty hanging, mounting, and fastening.

Grade B8 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges. They have good chemical resistance.

A distorted thread grips the screw to resist loosening.

Made of 18-8 stainless steel, these inserts have good corrosion resistance.

These inserts are made to stringent military specifications.

These inserts come with an installation tool. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts.

A black-phosphate finish provides mild corrosion resistance.
