Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws.

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

Made from alloy steel, these inch size set screws have a thin edge that digs into hard surfaces for a secure hold.

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

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

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.

These nuts have excellent chemical resistance and can be used in saltwater environments.

Fiberglass nuts are stronger than nylon 6/6 nuts. They resist acids, solvents, salt water, and oil.

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 nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 2 steel, so they can be used for fastening panels and other light duty fastening applications

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 corrosion resistant in wet environments, electrically conductive, and nonmagnetic.

These nuts have good chemical resistance.

Made from Grade 5 steel, these inch-sized locknuts are suitable for fastening most machinery and equipment.

These locknuts have good chemical resistance.

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.

Grade 5 locknuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut.

Threads at the top of these locknuts expand to grip the bolt on all sides for a stronger hold than distorted thread locknuts.

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

These Grade 8 locknuts are about three times stronger than low-strength steel distorted-thread locknuts.

These locknuts have good chemical resistance.

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

About two-thirds the height of standard steel-insert locknuts, use these locknuts in low-clearance applications or jam one against a hex nut to hold it in place.

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel flange nuts.

Made from 18-8 stainless steel, these flange nuts have good chemical resistance.

About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.

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

Use these tube-end weld nuts with left-hand threaded fasteners.

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

These are Grade 8 threaded rods.

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.

A black-phosphate finish provides mild corrosion resistance.
