How to choose

Start with the drive size: match the square drive of the ratchet or impact wrench you already use. For ratchets, see Japanese ratchet handles.
6-point or 12-point: Ko-ken RS3400M/12 (6-point) and RS3405M/12 (12-point) both cover 8-19 mm in 12 pieces; the 1/2" RS4400M/10 and RS4405M/10 are the same pairing (per the product names).
SAE (inch) sizes: ENGINEER TWS-01, Ko-ken RS3400A/9 and NEPROS NTB306BA.
With an impact wrench: choose sockets with "Impact" in the product name (the 1/2", 3/4" and 1" impact tables above).
Wheel nuts: in 1/2" drive, KTC TBP4903, Ko-ken 14201M and 14218M; in 3/4" and 1" drive, the KTC ABP6 / ABP8 combination sockets.
Tight spaces: TONE HRM311F and VESSEL WSA209PS; see also Japanese ratchet tools for tight spaces.
