Every good tool set needs wrenches and unless you’re an auto mechanic you can tackle most projects with two adjustable wrenches – one small, one large. This Wrench Set comes with both a 6 inch and 10 inch wrench in heavy-duty chromium-vanadium steel with smooth adjustment gears labeled in centimeters and inches. Use these to grip and tighten nuts and bolts, plumbing work, bicycle repair, and so much more.
