● Features (Manufacturer Specification)
✓ Ko-ken states the advantages of the thin-walled design are light weight for easier handling and the flexibility to reach into a narrow work space.
✓ Ko-ken notes that standard sockets follow ISO / DIN / ANSI norms, whereas wheel nut sockets are dedicated sockets designed around the job of tightening and loosening wheel nuts and bolts.
✓ Three sizes cover the common wheel nut sizes: 17, 19 and 21 mm.
✓ 6-point profile, 110 mm overall length on each socket.
✓ Colour coded so the right size can be picked up without measuring.
✓ Resin protector around the socket body, which dealers describe as removable.
✓ 1/2 in square drive, for use with an impact wrench or a hand ratchet.

● Before You Buy
Sockets only. No impact wrench, ratchet, extension bar or case is part of this listing.
Pins, O-rings and C-rings are sold separately. Ko-ken lists C-ring type C41 and pin / O-ring types A41 and B41 as the matching parts. None of them is supplied with this set.
Ko-ken's own warning: because these are thin-walled for wheel work, their load rating is lower than a standard socket, and over-torquing can crack the socket. Please observe the correct wheel nut torque.
Dedicated wheel nut sockets. They are not general-purpose impact sockets and should not be used for heavy general work.
Metric sizes only — 17, 19 and 21 mm. There is no imperial size in this set.
Japanese domestic release — any printed material is in Japanese.
A professional hand tool. Correct use and torque are the user's responsibility.
