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.

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.

A black-phosphate finish provides mild corrosion resistance.

These assortments include various sizes of thread-locking inserts.

Adhesive on both the internal and external threads keeps these inserts in place and holds screws tight.

A black-phosphate finish provides mild 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.

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.

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

These inserts have a high strength-to-weight ratio and resist acids and salt water better than nickel alloy and stainless steel inserts.

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.

Without a prong to break off and retrieve, these inserts are often used where debris could cause damage.

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

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

Made from brass, these inserts are nonmagnetic, corrosion resistant, and electrically conductive.

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

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

A closed end seals out elements and protects the threads on these inserts from debris.

The most corrosion resistant tee nut inserts we offer, these inserts stand up to chemicals and salt water.

Ridges on the barrel of these inserts make them less likely to split hardwood than inserts with prongs. They're often used in wood that has been cut across the growth rings.

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

Large threads cut into softwood such as particleboard for a strong hold.

Assortments include various sizes of tapping inserts for hardwood.

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

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

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

Wedges under the flange lock the nut in place in soft materials such as brass and aluminum.

A nonconductive rubber coating insulates the nut from electricity, seals out moisture, and damps vibration.

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.

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

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.
