Change thread sizes or types, such as fine to coarse threads, on parts without changing gender.

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.

Made of 18-8 stainless steel, these inserts have better corrosion resistance than black-phosphate steel.

These inserts are the most corrosion-resistant thread-locking inserts we offer.

Made of Nitronic 60 stainless steel, these inserts prevent the screw from binding or sticking without any coating or lubricant that could contaminate particle-free environments.

Made of Nitronic 60 stainless steel, these inserts prevent the screw from binding or sticking without any coating or lubricant that could contaminate particle-free environments.

Assortments include various sizes of helical inserts and a tap, a drill bit, and an installation tool for each thread size.

A dry film keeps the screw from sticking or binding in these inserts during installation.

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

The strongest key-locking inserts we offer, these inserts are made to stringent military specifications.

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

These inserts cut their own threads in soft metals such as aluminum, so there's no need to tap the hole. Also known as Tap-Lok inserts.

The tapered shape makes it easier to guide these inserts into a hole during installation. Use a drill bit to create a straight hole, then taper the top half.

Install these inserts into plastic parts to create a secure base for fasteners.

Made from brass, these inserts are electrically conductive, nonmagnetic, and have good corrosion resistance.

These 18-8 stainless steel inserts have better corrosion resistance than brass inserts and may be mildly magnetic.

These aluminum inserts are 70% lighter than brass inserts, electrically conductive, and nonmagnetic. They have good corrosion resistance, which is comparable to brass but not as good as stainless steel.

The flange keeps these inserts from pulling through a hole. Press them in from the underside of material, and install a screw from the top of material.

These 18-8 stainless steel inserts have better corrosion resistance than aluminum inserts and may be mildly magnetic.

Push down on the inside of these inserts with an installation tool and they expand to hold firm in surrounding material.

These 18-8 stainless steel inserts have excellent resistance to chemicals and may be mildly magnetic.

Assortments include various sizes of tapping inserts for hardwood.

The flange keeps these inserts from being pulled through a hole and provides a load bearing surface.

Assortments include various sizes of tapping inserts for softwood.

An open end allows long screws and bolts to pass through the insert.

Knurls hold these inserts in hardwoods such as oak, maple, and walnut to prevent twisting.

These 18-8 stainless steel tee nut inserts have better corrosion resistance than zinc-plated steel tee nut inserts.

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

These aluminum rivet nuts are one-third the weight of steel rivet nuts and have mild corrosion resistance.

About twice as strong as aluminum rivet nuts, these low-profile rivet nuts have a cadmium or tin-zinc plating for corrosion resistance.

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

About twice as strong as aluminum rivet nuts, these rivet nuts are zinc plated for mild corrosion resistance.

These aluminum rivet nuts are one-third the weight of steel rivet nuts and have mild corrosion resistance.

Threads float inside the nut so you can install a screw at a slight angle to align with off-center parts. They’re also known as Riv-Float nuts.

A ribbed-shaped body holds the nut in place so it won't move when tightening a screw. Assortments contain rivet nuts, mandrels, nosepieces, and a plier-style installation tool.
