The Snap-on 1/4″ Hex Drive Round Swivel Head Bit Driver Ratchet features a magnetic bit retention. The ratchet head swivels 260 degrees to fit into tight work areas, includes a 72-tooth gear for five degrees of swing arc, and has shorter movement between tooth engagement. Eight teeth are always in contact with the gear for strength and durability, and an adjustable yoke screw allows the head to be tightened into a fixed position. The ratchet has a nickel chrome finish that resists corrosion, and it comes in standard (No. TNFM72), soft grip (No. THNFM72), and hard handle (No. THNFDM72R) versions.
