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.

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.

These inserts are made to stringent military specifications.

The strongest key-locking inserts we offer, 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.

Weld these nuts to stainless steel surfaces.

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 nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold.

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

Projections on the base concentrate the weld and provide room for heat to dissipate.

These studs are also known as hanger bolts—use them to hang, mount, and fasten parts to wood structures.

Slip these inserts into tubular legs to quickly add threads for attaching leveling mounts. They’re often used in the legs of light equipment and furniture.
