Double Male Threaded Adapter

This stainless steel adapter bridges 3/8" and 1/4" threads, letting photographers, videographers and audio professionals mount cameras, lenses and accessories that use different thread standards. It is a compact connector designed for studio and location work.

Capacity and headroom

Weighing .7 oz (20g) with a 26mm width, it adds negligible mass to a rig while providing a secure mechanical joint for typical lighting and camera gear. It is not suited for heavy loads that exceed the shear strength of the smaller 1/4" thread.

Replaces single-thread adapters

The double male design removes the need for separate step-up or step-down rings when joining two female-threaded components. The upgrade is worthwhile whenever you regularly switch between 3/8" and 1/4" mounts and want one durable piece instead of multiple loose parts.

Questions about this item

Can I use this 0.7 oz adapter to connect my older 1/4" tripod head to a 3/8" light stand?

Yes, the double male threads convert between 3/8" and 1/4" sizes so you can mount the head directly onto the stand.

How do I confirm the stainless steel adapter is seated correctly after installation?

Both threaded ends should engage fully with no visible gap and the connected gear must not wobble when tightened.

Does the 26 mm wide adapter ship with any washers or tools, or must I buy them separately?

The box contains only the adapter itself; washers and tools are not included and must be sourced separately.
