A ratchet handle is used with sockets to tighten or loosen bolts, nuts, and other fasteners that are difficult to turn by hand. Its internal gear mechanism allows users to rotate the fastener in one direction while resetting the handle in the opposite direction without removing the tool from the socket.
Compared with standard handles, a ratchet handle improves working efficiency by reducing the need to repeatedly lift, reposition, and reinsert the tool. This makes it especially useful for repair, maintenance, and assembly work where faster operation and better handling are required.
Ratchet handles can be classified by gear count, including 24T, 36T, 48T, 72T, 92T, and 108T designs. A higher gear count provides a smaller swing arc, allowing users to operate more easily in narrow or limited working spaces.
