a devious fault....
G'day,
a few years ago I picked up a pack of 10 x 2" #2 Philips hex drivers, Trojan brand, that went into 'stock'. Diving into the box a few days ago and damn things wont enter any driving socket here, the calipers tell me that they measure 6.4mm, all good....
then it dawned on me, check out the socket end. Whatever they have used to finish the end chamfer has been so blunt that it has rolled a small portion of the chamfer over onto the hex section, just enough to put the extreme end oversize.
Luckily, the end is not hardened, a few strokes with a sharp file and it's fixed - I wonder how many of these guys went into the bin..... damn poor quality control....
Trojan, just another brand name living on it's past glories.... :disappr:
cheers,
Bob
