For a 6-inch adjustable wrench, performance means jaw capacity and adjustment: the WORKPRO black wrench states a 1-inch jaw, while the WORKPRO pink wrench states a 15/16-inch and 24mm jaw. Safety points come from stated standards only: ANSI on the WORKPRO black wrench and ASME on the CRAFTSMAN wrench. How we pick explains the weights.

What the listings tell you
Jaw capacity: from 3/4 inch to 1 inch
Jaw capacity splits the picks: 1 inch on the WORKPRO black wrench, 15/16 inch and 24mm on the WORKPRO pink wrench, and 3/4 inch and 19mm on the Mr. Pen wrench, with no jaw figure stated on the CRAFTSMAN wrench or the Crescent wrench. A buyer who wants the widest stated jaw suits the WORKPRO black wrench, while a buyer who works fasteners up to 3/4 inch suits the Mr. Pen wrench. All five picks state metric and SAE scales, so fastener size reads either way. See our best adjustable wrench guide for more wrenches.
Steel and finish: what the listings state
Steel splits the picks: Chrome Vanadium Steel on both WORKPRO wrenches, chrome alloy steel on the Crescent wrench, alloy steel on the CRAFTSMAN wrench and heat treated carbon steel on the Mr. Pen wrench. Finish splits them too: black oxide on both WORKPRO wrenches and the Crescent wrench, and chrome on the CRAFTSMAN wrench. A buyer who wants a black oxide finish suits any of the three black oxide picks, while a buyer who wants a chrome finish suits the CRAFTSMAN wrench. See our best wide jaw adjustable wrench guide for wider jaws.
Adjustment and grip: knurls, springs and handles
Adjustment splits the picks: a precision-machined slide jaw and worm gear on the WORKPRO black wrench and the Mr. Pen wrench, a flexible knurl with a hex jaw on the WORKPRO pink wrench, and a tension spring on the Crescent wrench. Grip splits them too: an ergonomic grip on the WORKPRO black wrench, a regular non-slip grip handle on the Crescent wrench, and a wider handle on the Crescent wrench for less stress to the hand. A buyer who wants a hang hole suits the WORKPRO black wrench, which states a round hole at the tail. See our best 8 inch adjustable wrench guide for a larger size.
Weight: from ounces to kilograms
Weight splits the picks: 5.28 ounces on the WORKPRO pink wrench, 6.4 ounces on the Crescent wrench and 0.14 kg on the Mr. Pen wrench, with no weight stated on the WORKPRO black wrench. The CRAFTSMAN weight is stated as 0.27 g, which looks like a listing error and is not relied on here. A buyer who wants the lightest stated weight suits the WORKPRO pink wrench at 5.28 ounces.
