Tekton 1/2 inch drive ratchets have a 90-tooth gear that produces a working swing arc of 4 degrees. The single half-moon pawl maintains 9 teeth engaged with the gear at all times, ensuring that it won't slip or skip under stress. The quick-release drive tang retains sockets with a spring-actuated detent ball—press the release button to easily add to or drop sockets from the drive tang. The soft overmold grip and rounded oval shape of the comfort grip handle support your palm and fingers. Unlike conventional "low profile" designs that focus on controlling only the thickness of the head, we reduced the size in every dimension: length, width, and height. Tekton ratchets meet (and most far exceed) the industry standard for proof torque, a measure of strength verified by a single-cycle test that applies torque until the specified value is reached without failure or any permanent deformation.
