This would be a good thread to answer the following:

Every so often I find a spec. for a small fastener in inch pounds and my wrenches are foot pounds.

So 80 inch pounds = what & how did you convert it?

80 inch lbs = 6.66666667 ft lbs.

yeah, that is what the google calculator gave me when I entered "80 inch pounds in foot pounds" in the search field:
80 inch pound force = 6.66666667 foot pounds

so divide the inch spec by 12, makes sense

Thanks

When I worked for Electromotive (Nissan GTP, not ECU's) years ago the engine builders swore by the old beam type torque wrenches (non-clicking). They felt they were just as accurate and they didn't have to rely on a click, they just watched the guage. Those 3 litre V-6 turbo's made over 1000hp on the dyno. I've had a 1/2" drive Snap On just like in the photo above for atleast 20 years and I'm sure it will pass on to one of my heirs still in perfect working condition. I bought it cheap at a pawn shop.

I do know that many people tend to still "push through the click" and inadvertently over torque but I don't expect that you'd do that. I always "sneak up on the click" and watch for additional movement of the socket when multi-clicking.

That's the issue with the click type torque wrenches. Many people feel that the click is some kind of stop on torque application. Its not. You can apply any amount of torque right on past the click. Its a basic operator error thing.

I don't do that myself and sneak up on the number as you do. If I'm in a good position I watch the digital display just like Tom's guys above looked a the beam scale.

This is where the smaller wrench comes in; larger wrenches don't read that low.
