Selecting the right option
Match the 1/2 in square drive to your impact wrench, then choose the size that fits the fastener. Dimensions are shown with the labels used in the catalogue table (D1, D2 and H). The catalogue footnotes list these retaining parts for the sockets: pin A41 with O-ring B41 or C-ring C41; pin A42 with O-ring B42 or C-ring C42. The part for each size is shown in its specifications. The catalogue lists the pins, O-rings and C-rings as separate packs (pages 270 and 271) and does not say whether any are supplied with the socket. (manufacturer-stated) 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.
