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.

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

A black-phosphate finish provides mild corrosion resistance.

These inserts are made to stringent military specifications.

Forming the strongest hold of any of our threaded inserts, these inserts have a distorted internal thread to lock screws into place and keys that drive into surrounding material to prevent slipping and rotating.

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.

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

A distorted thread grips the screw to resist loosening.

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.

Inserts come with a through-hole tap and installation tool.

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.

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

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.

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.

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.

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

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

Stronger than stainless steel, these nuts are comparable in strength to Grade 9 bolts.
