metal arse tool cabinet.

I had to giggle when it came to fixing the castors on. These are the supplied M8 machine screws:

Do they
really think that four castors attached to a thin bit of sheet metal requires 16 x 8.8 grade bolts, or are these the special chinesium version that has 8.8% of the strength of a normal ungraded machine screw? A quick look-up says that 16 grade 8.8 M8 machine screws have a combined guaranteed load of 337.6 kN (that's 34.4 tonnes or 75,895 lbf, or just under 7 male Indian elephants, or a bit over 4 1/2 London buses). Hmm, bit of overkill, slightly; only by a smidgeon though.
