Double Open Ended Spanner/Wrench Set 6mm-46mm Metric

Measure across the flat faces of the bolt head or nut with a caliper or ruler — this is the wrench size you need. For example, an M10 bolt typically uses a 17mm wrench. Each variant in this set lists both jaw sizes (e.g., "16–18mm"), so you get two usable ends per wrench.

No. This set is sized to metric standards only. Using a metric wrench on an imperial fastener (or vice versa) risks rounding the fastener corners. If you need SAE sizes, please contact us to confirm availability of imperial options.

The wrenches are drop-forged from chrome vanadium steel (Cr-V), a common alloy for professional-grade hand tools. Drop-forging aligns the metal grain for higher tensile strength and fatigue resistance compared to cast or stamped steel tools.

The polished chrome plating provides a barrier against surface oxidation and is resistant to oil, grease, and moderate moisture exposure. For long-term storage in high-humidity environments, wiping the tool with a light machine oil after use is recommended.

Yes. The drop-forged Cr-V construction is suited for the torque demands of automotive suspension bolts, exhaust manifold nuts, and similar high-load fasteners. Always ensure the jaw is fully seated on the flat faces of the fastener before applying torque to avoid slippage.

Each size is sold individually — you select the jaw size pair you need (e.g., "22–24mm") and add just that wrench to your cart. This lets you fill gaps in an existing set without purchasing sizes you already own.

The jaws are set at a standard 15° offset angle relative to the handle centerline. This offset provides clearance to swing the wrench in confined spaces — such as between engine components or behind pipe fittings — where a straight-jaw wrench would not have enough arc to reposition.
