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

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.

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

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.

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.

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.

These metric-sized coupling nuts are Class 10 steel, so they’re about 25% stronger than medium-strength steel coupling nuts.

Choose these locknuts to fasten standard metric threads. They’re Class 8 steel, so they can be used in most fastening applications.

For light duty applications, choose these metric-sized coupling nuts.

Comparable in strength to Grade 9 bolts, these coupling nuts are about 20% stronger than high-strength steel coupling nuts. Available in inch thread sizes.

These metric coupling nuts have good chemical resistance.

More corrosion resistant than 18-8 stainless steel coupling nuts, these metric nuts have excellent resistance to chemicals and salt water.

Plastic coupling nuts are chemical resistant, nonconductive, and lightweight.

A smooth rounded body provides a finished look.

Known for their strength, steel coupling nuts are available with a corrosion-resistant finish.

These standoffs are made to NAS specifications.

Protect components from electrical charges.

The magnetic end of these standoffs makes it easy to temporarily mount or reposition components on magnetic surfaces.

A recess under the hex clinches a panel for a strong hold that won't push, pull, or twist out. When mounted with a lever press, the hex sits flush with the surface and the open end creates a through hole.
