Torque wrench woes - postoak_imp - 08-10-2018
Twice now, I have snapped bolts when my torque wrench didn't "click" at the set weight. This is with two different torque wrenches. (I suppose I could have made a mistake in the setting, but I don't think so.) Anybody every have this happen to them?
I no longer trust that type of torque wrench! I am going to go back to the old style with the needle. At least with it you can see where you are in a continuum on the torque scale.
What's annoying is in both these cases I could have just gone by feel and been just fine.

No, I haven't but fear it could happen, although I mostly use it for torquing the rear axle nut and doubt I'd ever snap that baby off.
RE: Torque wrench woes - postoak_imp - 08-10-2018
Yeah, after I posted I did a google search on something like this happening and found some hits. I would never trust this type torque wrench again.

Always store that style of wrench with the tension off the spring (loosen all the way).
The smaller the wrench, the less 'click' they tend to make. You must keep an eye on them and watch and feel for the movement.
I'm not a fan of the old school needle bar- too much leeway.
If I used a tq wrench more often on critical stuff (engine internals) I would go in the other direction and get a good digital one.

I have a nice one but generally just go by feel. experience on what diameter the bolt , type of metal and amount of stress the part may take has allowed me to never over tighten or anything come loose. have used Lock tight on my Harley's but that problem has been solved ..........

I use my elbow as a torque wrench. Never snapped a bolt, and never had a leak.

Q1.
How did you approach torquing...did you try to torque nut/bolt that was already tight/torqued or first you cracked it loose...was your bolt/nut lubed or dry and of what size and length??...it matters
Q2 What was your TW set at?
Hope you are not talking about angle torque and your wrench was set OK and in good working condition (always store TW in rest position)
The old style with needle, explains for itself

Hope you’ve never worked on engine internals, bearing clearances, etc.
Tq specs aren’t just for keeping bolts from falling out or snapping.

Yeah, I know to keep the wrench stored at zero, but admit I forgot this time -- maybe that did it. As for the smaller one, at the time I thought to myself that I had already tightened the nut past the the small value required, and maybe I did, but I doubt it.
The older needle type may not be as accurate, but at least you won't go way past the value called for waiting for a click.
As for the oil, I am usually just putting back on a bolt or nut I have previously removed with no additional oil added.
