Double Ring Spanner Wrench 5.7mm-41mm 1pc Metric Spanners 75 Offset Silver

Measure the across-flats (AF) dimension of your bolt head or nut using a caliper or ruler. Match that measurement to the corresponding wrench size — for example, a 17 mm bolt head requires the 17×19 variant. When in doubt, size up rather than down to avoid slippage.

The 75° offset tilts the ring ends relative to the handle, creating vertical clearance between your knuckles and the work surface. This is especially useful when tightening bolts recessed in engine blocks, flanges, or pipe fittings where a flat wrench would scrape against surrounding components.

Yes. Chrome vanadium (CrV) is the industry-standard alloy for hand tools requiring a balance of tensile strength, toughness, and resistance to fatigue. It handles the torque demands of automotive and industrial fastening without deforming under normal use conditions.

The polished chrome plating provides a corrosion-resistant barrier suitable for typical workshop environments. For prolonged exposure to moisture or outdoor storage, wipe the wrench with a light machine oil after use to maintain the finish and extend service life.

This wrench is sized to metric standards. While some metric sizes are close to SAE equivalents (e.g., 13 mm ≈ 1/2"), using a metric wrench on an SAE fastener — or vice versa — risks rounding the bolt head. For SAE fasteners, use a wrench sized specifically in inches.

Each order contains 1 pc of the selected size. This lets you purchase only the specific size you need to fill a gap in your toolkit, or buy multiple sizes individually to build a custom set at your own pace.

A combination spanner has one open-end jaw and one ring end. A double ring spanner has two closed ring ends — typically two different sizes — giving you two secure ring-contact options in a single tool. The closed ring design also allows more torque to be applied safely compared to an open-end jaw.
