1/4-inch thread
Also known as: 1/4-20 thread, tripod thread, tripod screw
The standard tripod screw thread used on cameras, tripods, lights and accessories worldwide. Action cameras use adapters or built-in threads to connect to it.

What it means
Nearly every tripod, light stand, clamp and camera accessory in photography uses the same screw: a 1/4-inch thread with 20 threads per inch, often written as 1/4-20. A camera with a matching hole screws straight onto any tripod or accessory with this thread.
Action cameras traditionally used mounting fingers instead, so adapters convert between the two. Some newer action cameras, pocket gimbals and accessory frames include a 1/4-inch thread directly, which opens up the whole world of photo and video accessories.
Larger 3/8-inch threads exist for heavy professional gear, and adapters convert between the two sizes.
How it works in practice
A small fingers-to-thread adapter is one of the most useful items in a camera bag. It connects an action camera to a phone tripod, a light stand, a clamp or a car mount from the photo world.
When screwing a camera onto a tripod, tighten until snug, then stop. Many tripod heads have a locking ring that holds the camera without over-tightening the screw itself.
Arca-style quick-release plates also screw on via 1/4-inch threads, making it easy to switch a camera between tripods and gimbals without unscrewing anything each time.
What to watch out for
Forcing a misaligned screw strips the thread, especially in plastic housings. Start by hand, and make sure the thread is straight before tightening. If it resists after a turn or two, back it out and try again rather than forcing it.
Over-tightening can crack plastic bases or damage internal threads in small cameras and phone clamps. Snug is enough.
A single screw can let the camera rotate under load, for example on a long arm in wind. Use anti-twist pins, rubber pads or a locking ring to keep the angle fixed. For anything that moves fast, a dedicated action mount with fingers or a quick-release holds better than a single screw, and a tether adds a final layer of safety.
How RawClip handles it
Static clips from a tripod or stand add stable, wide context to action footage. Upload them together with your mounted POV clips, and RawClip combines the best moments into one highlight.
