Overview
GRENPRO's 071603 wrench measures 12.2 inches long with a 23 millimeter jaw capacity, sizing it for mid range nuts and bolts rather than very large fasteners.
A 12.2 inch handle length is typical of full size adjustable wrenches, giving decent leverage without excessive bulk. The 23 millimeter capacity covers many common household and automotive fastener sizes, though the listing does not state whether the jaw is fixed or adjustable, or what material the wrench is made from.
