Spacers and Standoffs

Male-Female Threaded Hex Standoffs

Position components in assemblies, as well as separate or connect parts with these standoffs.

Thread-Locking Male-Female
Threaded Hex Standoffs

A nylon patch bonded to the threads adds friction, preventing these standoffs from loosening from vibration.

Female Threaded Hex Standoffs

Female Threaded Round Standoffs

Miniature Press-Fit Threaded
Standoffs with Open End

These standoffs are designed to fit in the limited space of compact electronics such as laptops and hand-held devices.

Thread Adapters

Inch-to-Inch Male-Female Hex Thread Adapters

Change thread sizes or types, such as fine to coarse threads, on parts without changing gender.

Inch-to-Metric Male-Female Hex Thread Adapters

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.

Slotted-Drive Male-Female Round Thread Adapters

Inch-to-Inch Female Hex Thread Adapters

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

Inch-to-Metric Female Hex Thread Adapters

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.

Inch-to-Inch Male Hex Thread Adapters

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.

Inch-to-Metric Male Hex Thread Adapters

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.
