...would STILL not fit on a "13.8 mm" bolt-head. Or what the FUCK were you trying to say?!? For once, your body text was much clearer than the headline. Too bad the headline was total gibberish...

Yeah, sure, it COULD be that your el-cheapo Chinese tools(*) have such humongously sloppy "tolerance differences" that a nominally "14 mm" wrench would fit on a 9/16" (14,2875 mm) bolt-head. Or maybe your bolts are Chinese too -- WTF do I know (or care)...

Anyway, that's what I frigging SAID -- "Either your bolts or your wrenches are off measure" -- before, isn't it? So, uhmm... What the fucking fuck are you objecting to here???




(*) BTW, haven't you ever heard the old saying, "the poor man can't afford to buy cheap"?
