Smooth and refined, the 90-tooth ratcheting system offers a concise 4� swing arc that works in the tightest spaces. Depending on the drive size, the single half-moon pawl maintains 6 to 9 teeth (more than most dual pawl designs) in contact with the gear at all times, ensuring it will never slip or skip under stress.

To aid the initial wear-in of mated parts and to keep them moving smoothly, the internals are lubricated with a few drops of light machine oil. The design of the head and ratcheting mechanism allows it to be disassembled for periodic cleaning or lubrication.

Ultra-Compact Head

In most situations, access to tight spaces isn't limited by the thickness of the head because there's still the length of the socket or sometimes an extension to account for. Rather, it's usually a head that's too wide or too long that gets in the way. 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. And most importantly, we did it without compromising strength.

Lock-On, Quick-Release Drive

The drive tang engages and retains sockets with a detent ball backed by a locking pin. Once it's engaged, the socket is securely locked on�it won't accidentally fall off or be pulled off by sticking on a fastener. Pressing the release button drops the detent ball out of the way so sockets can effortlessly slide on to or simply fall off the drive tang, even making a one-handed socket change possible.
