Description

Ratchet Set, 3-Piece (1/4 in., 3/8 in., 1/2 in.)
90-tooth gear produces a working swing arc of just 4 degrees
Ultra-compact head is smaller than "low profile"—it's reduced in height, width, and length
Classic pull-release drive tang retains sockets with a spring-actuated detent ball
Sleek and simple handle design offers comfort and control in a variety of hand positions
90-Tooth Gear
= 4° Swing Arc
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.
Classic
Non-Quick-Release Drive
The drive tang engages and retains sockets with a spring-actuated detent ball. This lean, reliable design uses only two small moving parts—the ball and spring. This means the drive tang can be solid end to end and therefore slightly stronger in this area than ratchets with a locking pin, which require a hole drilled lengthwise through the center of the drive tang. Sockets are attached and removed by simply pushing them on and pulling them off.
