Tekton 1/4, 3/8, and 1/2 inch drive flex head stubby ratchets have a non-locking joint that gives the head a continuous 180-degree range of motion. It has just the right amount of tension to hold any position without flopping over. The 90-tooth gear results in a 4-degree swing arc. 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. Unlike conventional "low profile" designs that focus on controlling only the thickness of the head, we reduced the size in every dimension: height, width, and length. 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. We name our ratchets and breaker bars according to their effective working length, which is measured from the center of the drive tang to the end of the handle. The handle is kept as short as possible while still providing meaningful leverage in tight spaces. A defined finger groove provides control, and the flared end helps keep your grip secure. This set includes 1/4, 3/8, and 1/2 inch drive flex head quick-release stubby ratchets.
