Really Right Stuff has always rejected coin-slotted screws for our quick-release plates, no matter how convenient they may appear. Sufficient torque to properly fix the screw just can't be generated with a coin. Instead, we've always chosen hex-socket screws to anchor our quick-release plates. Hex keys deliver more than enough torque for the job, are compact, inexpensive, and universally available. We also include US-made Bondhus® hex keys with all our screws because of their unsurpassed dimensional consistency and ultra-high corrosion resistance.
Really Right Stuff captive style screws are custom machined with part of the shaft unthreaded. This allows our plates to be installed or removed with minimal risk of cross-threading, and keeps the screw installed in the mounting plate which saves time and further minimizes the risk of losing the mounting screw.
The B103 is a longer captive screw for camera plates with deeper sockets that use 1/4"-20 threading.
