20 mm Combination Wrench

This Westward combination wrench fits 20 mm metric fasteners with both an open end and a box end. It is built from alloy steel with a satin finish for corrosion resistance. The tool suits mechanics and technicians who need a single wrench for common automotive or industrial bolts.

15 Degree Offset for Clearance

The box end features a 15 degree offset and a 15 degree opening angle to clear obstructions around the fastener. Head thickness measures 7/16 in to engage bolt heads securely. This geometry helps apply torque in tight engine bays or machinery without rounding corners.

10 5/8 Inch Overall Length

At 10 5/8 in long, the wrench provides usable leverage for standard maintenance tasks. The rounded box-end profile distributes force across fastener flats rather than corners. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm.

Questions about this item

How do I seat the 20 mm box end on a tight bolt without rounding it?

Engage the 15 degree offset box end fully before applying force; the 15 degree opening angle lets you swing the wrench in confined space without slipping off the flats.

What wear should I watch for on the alloy steel jaws over time?

Inspect the 7/16 in head thickness for thinning or spreading; replace the wrench if the 20 mm opening no longer grips the fastener securely.

At what point does the 10 5/8 in handle length stop giving enough leverage for stubborn fasteners?

When the required torque exceeds what the 10 5/8 in lever arm can deliver without excessive body force, switch to a longer breaker bar or impact tool.
