Check the listing for details. Laser Tools Wheel Nut Socket Set 18.5 & 19.5mm 8618. Condition: New. Listed at 52.37 USD. A pair of half sized single hex (6pt) wheel nut sockets, specially designed to fit 19mm factory wheel nuts with permanently fitted chromium-plated caps. These start off as a whole size, but over time due to the combination of corrosion and impact tool use, the wheel nuts can swell by up to 0.5mm. These impact sockets are supplied as 18.5mm and a 19.5mm pair to overcome this issue, with the 19.5mm designed to fit over damaged or swollen chrome caps and the 18.5mm designed to fit wheel nuts where the caps are now missing.
