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.

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 tighten when turned 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.

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

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

These nuts are about 25% stronger than medium-strength steel thin hex nuts. Available in inch thread sizes.

Because they’re about 10% wider and taller than standard hex nuts, these heavy hex nuts distribute the load over a large area. Grade 2H nuts are comparable in strength to Grade 9 bolts.

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.

Comparable in strength to Grade 8 bolts, these locknuts are about three times stronger than the same locknut made with low-strength steel.

Known for their strength, these steel locknuts are cadmium plated to resist corrosion in wet environments.

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 coupling nuts. Furnished in inch thread sizes.

About half the strength of medium-strength steel cap nuts, use them in light duty fastening applications, such as securing access panels.

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

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

Inserts come with a through-hole tap and installation tool.

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

Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.
