Many of the Hornets, Mosquito ASK13 came out with a 3 bolt of 6mm diameter. These can easily sheer one bolt and usually this can be detected by a CLICK CLICK CLICK. I would recommend with Allen key these be checked for tightness say two or three times a year.
These hubs with bolt sheering proved to be a problem. For a while Tost drilled these bolts out to 8mm and grade 8 bolts of appropriate length were used but soon after this Tost changed their moulds for split his to incorporate 6 bolts and these were all 6mm again and these have been have been all but trouble free for sheering bolts. All I am saying if you have the older 3 bolt hubs consider checking the bolts regularly and consider having a few spare 6mm bolts Ian McPhee 0428847642 Box 657 Byron Bay NSW 2481
