Are you familiar with AS-954? I doubt it, because you'd understand that it requires 12-point to conform to the requirement of AS870, meaning that they shall transmit torque to the fastener without bearing on the outer 5% of the fastener's wrenching points. Now think about that for a moment. There would never be a conformance standard created unless there was an issue in the first place. And the issue is that 12-point tools do not put the same stress on the same surface area as a 6-point tool used on a 6-point fastener. Sorry, but you don't know what you're talking about.
Not sure why you keep quoting SAE AS-954, which is a spec for 12 pt sockets on 12 pt fasteners. The 5% requirement is also held for hex fastener and hex sockets in other Standards...
This discussion was about 12 pt on a 6 pt fastener. I think the picture of the 6 fasteners is telling, as there is virtually no difference between the 12 and 6 pt tool marks, and considering it was different makes of sockets, is even more telling.
The real issue with round off, is either soft fasteners, poorly fitting tools (typically open ends where not needed) or both.
(Any one had any experience rounding off a grade 8 bolt? grade 5? (Or their metric equivalents) More likely grade 3 or some soft material like brass...)


cracks me up how guys just pull **** out of thin air to make a point. i would bet that every guy who ******* about those worthless crappy 12 pt sockets has a whole box full of 12 point wrenches they love. i know some do but most don't have any 6 point wrenches. i have yet to have anyone explain to me how 12 pt wrenches can be so good and the norm while 12 point sockets are bad and the sure sign of a hack.
