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

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

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

Brass cap nuts are corrosion resistant in wet environments and electrically conductive.

An irregularly shaped thread grips the bolt for a stronger hold than nylon-insert cap locknuts.

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

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.

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

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

Also known as clinch style captive nuts, press these nuts into a drilled or punched hole with an arbor press or similar pressure tool.

Wings provide more leverage for greater torque while tightening than knurled-head thumb nuts.

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

A nylon insert grips threads to resist loosening.

These thumb nuts have an aluminum insert to withstand more torque than plastic thumb nuts during installation.

These nuts can be used in channels and tight spaces where round-base weld nuts won't fit.

Weld these nuts to uncoated steel surfaces.

Weld these nuts to flat and uneven uncoated steel surfaces for a strong permanent hold.

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

Use these tools to install most styles of rivet nuts. Use a wrench to hold the tool and a ratchet to tighten the nut.

Use these tools to install smooth and ribbed body rivet nuts. An indicator allows you to ensure your rivet nut installs correctly.
