21 mm Combination Wrench
The Westward 36A303 is a 21 mm combination wrench built from alloy steel with a chrome finish. It provides both an open end and a 15-degree offset box end for fastener access in automotive and general mechanical work. The overall length is 10 5/8 inches with a head thickness of 7/16 inch.
Suited for metric fasteners only
This wrench fits 21 mm metric hex fasteners and is not compatible with imperial sizes. Buyers who need a different metric size or a set covering multiple bolt diameters should look at other options. The fixed head offset angle of 15 degrees may not suit tasks requiring a straight or deeper offset profile.
21 mm head size decides fit
The single specification that determines whether this is the correct part is the 21 mm head size. It matches only fasteners with a 21 mm across-flats dimension. Verify the bolt or nut size before purchase to ensure compatibility.

Questions about this item
At what head offset angle does the 21 mm box end start to slip on a stubborn fastener?
The box end is offset 15 degrees, which gives clearance but can limit torque on severely rounded nuts.
How warm does the alloy steel get after a full day of high-torque automotive work?
The chrome-plated alloy steel absorbs hand heat but does not generate its own; it stays near ambient temperature during continuous use.
What drive-size ratchet or breaker bar fits the 21 mm open end for extra leverage?
The open end is a fixed 21 mm jaw; it does not accept a ratchet or breaker bar, so a larger wrench or cheater pipe is needed for more leverage.
