Key specifications

Weights and retaining part codes are manufacturer-stated (Ko-ken catalogue 2025-26). A dash means the figure is not published on this page.

Selecting the right option

Match the 3/4 in square drive to your impact wrench, then choose the size that fits the fastener. The Ko-ken impact catalogue (2021) describes thin walled impact sockets as having a straight shape body that allows deeper access in narrow spaces. (manufacturer-stated) Dimensions are shown with the labels used in the catalogue table (D1, D2, H1 and H2). The catalogue footnotes list these retaining parts for the sockets: pin A61 with O-ring B61 or C-ring C61; pin A62 with O-ring B62. 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.
