Rockn 3/8"-16 Female To 1/4"-20 Male Screw Adapter for Tripod and Camera

The Rockn 3/8"-16 Female To 1/4"-20 Male Screw Adapter is a nickel-plated brass adapter that lets you mount devices with a 1/4"-20 threaded mounting hole, such as a camera, onto a 3/8"-16 mounting screw. The surface is knurled for better grip, and an included washer helps protect the bottom of your camera or device from friction with the adapter.
