A ratchet consists of a bar or wheel fitted with angled teeth. Used to turn cogs and bolts, ratchets deliver maximum leverage for unloosening even the tightest nuts and bolts. The best products feature a moulded steel frame, a comfort-grip handle and a set of 72 teeth. A reversible ratchet allows you to screw or unscrew in both directions. You’ll find products from leading brands here, including Teng, Sealey and Bahco.
