What size izzit ???
 

While doing the 3M fuel system kit treatment on my '09 Fit this past weekend, I couldn't find the right size 1/4" drive socket (buried in some pile of crap) :confused: for the tiny band clamp bolt that secures the intake hose on the throttle body. Looked it up but doesn't give the head size. P/N lists as 90005-RGA-000 BOLT, CLAMP (4X25). The Phillips slot on it is smaller than normal and a screwdriver kinda slips and I don't wanna butcher it up (not that I'm in there that often). Tried a 5mm (too small) & 1/4" (too big) that's all I got at the moment. College Hills Honda tech thinks it might be 5.5mm, but not sure. Either that or maybe 7/32"? Would someone test theirs and lemme know? Then I can ebay the right size for my tools.

7/32" = .218" = 5.55mm
15/64 = .234" = 6mm

8mm. Everything on the car is metric being that it's a Japanese produced automobile. Edit may bad, it's not an 8mm. Just use a screwdriver to loosen the clamp

Found out a 7/32" fits nicely, which is .21875", .0022" larger than 5.5 mm. I'll get a small socket set for these occasional tiny bits.
