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

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

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

Made from 18-8 stainless steel, these metric nuts have good chemical resistance and may be mildly magnetic.

Made from nylon 6/6, these metric wing nuts are chemical resistant, nonconductive, and lightweight.

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

These metric thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The flange distributes pressure over a large area to reduce stress on your part.

Use these metric nuts in channels and tight spaces where round-base weld nuts won't fit.

A smooth base provides more contact with the mating surface than weld nuts with projections.

Weld these nuts to uncoated steel surfaces.

You can weld these metric nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold.

Threads float inside the retainer of these metric nuts so you can install a bolt at a slight angle to align with off center parts.

A hex-shaped body provides the highest twist resistance of any rivet nut.

The most corrosion resistant low-profile rivet nuts we offer, these stand up to chemicals.

Once installed these rivet nuts have a large back flange that distributes the load across a broad area for a strong hold in plastic and composites.

The thread area is enclosed, which prevents leakage past the threads from either side of your application.

Use these hex drive screws and binding barrels as a low-profile alternative to standard nut and bolt combinations.

These metric thumb screws have wings that provide more leverage than spade-head thumb screws for greater torque while tightening. A zinc plating provides corrosion resistance in wet environments.

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.

Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.

These steel studs are zinc plated to resist corrosion in wet environments.

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.
