The Ko-Ken PS6 is a rear wheel nut socket in 17, 19, 20 and 21 mm with a 3/4 in drive (manufacturer-stated). It is listed on the impact page of the catalogue.

Selecting the right option

Choose the size that matches your wheel nut; the table lists each size with its weight. The catalogue's safety notes say to select impact sockets only for electric or air impact wrenches, to wear safety goggles when using nut runners or impact wrenches, never to substitute a hand socket for an impact socket, and to replace sockets with cracked walls, battered points or other marks of wear (manufacturer-stated).
