TS-Optics 1/4" Photo Screw Cylinder Head Screw - length 12 mm

Inch screws with 1/4" thread

You can get normal screws with metric thread everywhere in the hardware store or in the qualified screw specialized trade. But what about the coveted customs screws? Almost every camera, spotting scope or binocular holder has the 1/4" internal thread, which is also called the "small photo thread". Exactly this thread has tilt heads or ball heads of photo tripods on the camera side.

With the appropriate inch screw you can attach, for example, your camera directly to dovetail bars or top panels.
