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

The standard for high-strength fastening.

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.

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

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

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

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 5 steel, so you can used these inch-sized nuts for most fastening applications.

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

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

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

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

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

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

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

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

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

These flange nuts have a black-oxide finish for mild corrosion resistance in dry environments.

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

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.

A black-phosphate finish provides mild corrosion resistance.

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

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

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

A distorted thread grips the screw to resist loosening.

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.

Use these nuts with a sleeve and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Also known as machinery eyebolts.
