Choosing Ratchets & Wrenches

How do I pick the right ratchet drive size?

Choose the drive size by the fastener size and torque you need — 1/4-inch for small fasteners and tight spaces, 3/8-inch for general automotive and mechanical work, and 1/2-inch for high-torque lug nuts and large bolts. A higher tooth count means a smaller swing arc, which is useful in confined areas.

When do I need a flex-head or swivel ratchet?

When fasteners sit at an angle or in recessed areas where a fixed-head ratchet cannot align. A flex or swivel head lets you keep the handle clear of obstructions while the socket stays on the fastener, improving access in tight engine bays and assemblies.
