ARES Professional 120-Tooth Ratchets need just 3-degrees of sweep for ratcheting action, making them ideal for close quarters work in tight spots. Made of chrome vanadium steel with a mirror polish finish and featuring a professional gear-to-gear pawl structure for increased durability, the ratchet set is built to last. The thumb switch on the back of each ratchet head allows for easy direction change while the contour forged handle makes these ratchets comfortable in the hand, reducing hand tension during use. Each ratchet is made to meet or exceed ANSI and ASME performance standards.
