this genuine Honda filter wrench has a 10mm nut welded to the filter cup so it slips into tight places. it does not have a 3/8" square drive. the wrench/socket size is 17 mm hex with the hole in the nut threaded 10mmx1.25 pitch. if the filter gets stuck in the cup you just thread a 10 mm bolt into the welded nut and this pushes out the filter from the cup.it pays to have and use the correct factory tool.
