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.

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.

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.

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

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

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

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

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

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

Square weld nuts have more weld points than hex weld nuts for a stronger hold. Use them on flat surfaces.

These nuts can be used in channels and tight spaces where round-base weld nuts won't fit.

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.
