The K-532 Camera Mounting Plate Combo Tool from Thinguma is a handy, take-anywhere multi-tool designed to tighten the mounting screws on most Arca-type compatible quick release plates. The larger edge of the tool fits any screw which utilizes a standard "flathead" slot, while the smaller edge fits into 5/32" (4mm) hex screws, the most common size used for most quick release plates. The tool itself is constructed of a durable steel alloy and features an integrated port for attaching the tool to any standard keyring—ensuring that the K-532 is with you whenever you need it.
