In addition to joining male- and female-threaded parts, these adapters can increase or decrease metric thread sizes and change the thread pitch.

Twist these adapters onto female metric threads to change pitch or switch thread sizes.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

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.

A closed-end tap, drill bit, and installation bit are included with these inserts.

A black-phosphate finish provides mild corrosion resistance.

Eliminating the need for primer, these inserts are coated to resist corrosion when installed in different materials.

Made of nickel alloy, these inserts are more resistant to acids and salt water than stainless steel inserts.

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

A distorted thread grips the screw to resist loosening.

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

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.

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.

70% lighter than stainless steel, these aluminum inserts are mildly corrosion resistant and nonmagnetic.

The barbed sides keep these securely in place even before a screw is installed.

Assortments include various sizes of inserts, a soldering iron, a ceramic insulation tube, and installation tips.

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

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

About twice as strong as aluminum rivet nuts, these steel 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.

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.
