Availability set by the retailer

The JTZWN 3/8" Offset Extension Wrench Set is an impact-ready offset ratchet extender designed to reach confined fasteners where a standard ratchet or wrench has little room to swing. The 17-inch (17 x 1.57 x 1.57 in) alloy steel body adds working reach for cramped engine-bay, under-sink, and assembly work while keeping the socket end close to the fastener. The offset design helps turn bolts in tight spaces across automotive, plumbing, and furniture repair tasks. A built-in direction selector lets you switch between tightening and loosening, then operate the wrench by hand or with a compatible 1/2" impact wrench. The included adapter set supports 1/4, 3/8, and 1/2-inch square-drive connections for sockets and compatible power tools. Engineered for a maximum manual torque of 74 ft-lb and an impact torque of 50 ft-lb, the tool is constructed from high-strength alloy steel with a rotating shaft mechanism for smooth operation. Ideal for reaching fasteners on water pumps, alternators, or parts hidden under the dash, allowing part removal without dismantling the entire surrounding assembly. Brand: JTZWN; Material: Alloy Steel; Item Length: 17 inches; Item Weight: 3.3 pounds; Color: Silver; Head Style: Square Drive; Operation Mode: Electric; Measurement Standard: SAE; Model Number: JTZWN-2502241. Perfect for professional mechanics and hobbyists working in narrow auto repair and hard-to-reach spaces.

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.
