STHIRA cross wrench works as a car wheel spanner for roadside tyre changes and routine lug nut removal. Its four socket openings fit 17mm, 19mm, 21mm and 23mm lug nuts, helping you select the matching size quickly.Use it as a tyre stepney wrench when changing a spare wheel at home, on the road or in a parking area. The folding design stores neatly in a vehicle tool compartment and is convenient to carry.Compared with a single straight wrench, the cross layout offers multiple socket sizes in one tool and provides two-hand handling during wheel work. The chrome-plated steel construction supports regular automotive use.Confirm the lug nut size before turning. Seat the socket fully on the nut, apply steady pressure, and avoid using an extension or impact tool. Wipe off dirt and moisture before storage.
