Teng Tools 20 mm Metric Combination Wrench - Chrome Vanadium Steel, 12-Point Ring End and Open End, 240 mm Length - 600520

This Teng Tools individual metric wrench delivers two fastener-gripping profiles in one chrome vanadium tool: an open-jaw end for quick side-on engagement and a 12-point ring end for secure, high-torque turning. That combination makes it a practical choice for the automotive and industrial mechanic who works with mid-range metric hardware daily.

The chrome vanadium steel forging resists bending under the working loads typical of brake, suspension, and drivetrain fasteners. Chrome plating over the entire surface guards against corrosion from moisture, brake fluid, and shop chemicals, while the polished finish helps you find the wrench quickly in a loaded drawer or under a vehicle.

The 12-point ring profile engages hex and double-hex bolt heads, giving you more repositioning options in the restricted clearance around engine accessories, exhaust manifolds, and frame rails. The open end adds speed when you can approach the fastener from the side and only need to run it down or break it loose before switching to the ring end for final torque.

At 240 mm (9.4 in) overall and 180 g, the handle provides a comfortable lever arm proportional to the 20 mm fastener class. Sold individually, this wrench lets you replace a single lost or damaged size, fill a gap in a partial set, or keep a dedicated tool at a specific work bay.

Teng Tools builds hand tools for working tradesmen who need reliable, properly finished equipment on the job every day.

• OPEN END AND 12-POINT RING END — The open-jaw side slides onto metric bolts and nuts from the side for rapid engagement in automotive and industrial maintenance tasks, while the 12-point ring end on the opposite side surrounds the fastener head for controlled, high-torque tightening and loosening. Switching between ends lets you work faster without reaching for a second tool or repositioning the vehicle on the lift.
• CHROME VANADIUM STEEL FORGING — The wrench body is forged from chrome vanadium steel, a material selected for its high tensile strength and resistance to bending under the substantial torque loads common in mid-range metric fastener work. This is the steel grade professional mechanics rely on for brake caliper bolts, suspension hardware, and manifold studs where tool failure can damage components or cause injury.
• POLISHED CHROME SURFACE — A bright chrome plating layer protects the underlying steel from rust, oil staining, and chemical attack in demanding shop environments. The reflective finish also improves visibility when working inside wheel wells, under dashboards, and around engine blocks where ambient light is limited, and it resists staining from brake fluid, penetrating oil, and degreaser contact.
• INDIVIDUAL 20 mm WRENCH — Sold as a single wrench so you can target the exact size you need without paying for sizes you already own. Ideal for restocking a worn-out favorite, adding a dedicated wrench to a secondary tool cart, or building a custom metric collection one size at a time. The size marking is forged or stamped into the body for permanent identification even after years of heavy use.
• OVERALL DIMENSIONS — Measures 240 mm (9.4 in) in total length and weighs 180 g, providing enough lever arm for effective torque on automotive-grade fasteners while remaining manageable for extended work sessions. The proportions balance reach and control for jobs like underhood maintenance, chassis repair, and equipment servicing where mid-range metric hardware is most common.
