Snap On Techangle torque wrench accuracy

[jgelack]

I recently picked up a Snap On 3/8 Techangle torque wrench (5-100lbs). Can anyone tell me how accurate this wrench is in the lower end of the torque range, say 5-20lbs? I have to torque something to 10nm (7ft lbs)which I know isn't a lot, but I want it to be accurate. I am just wondering how close I'll get with this wrench. Thanks

There is no way I would use that torque wrench at that low of a setting. I have a 1/4" drive inch lb Snap On I use for those types of bolts. What are you torquing, just curious.

I'm installing smog block off plates on my motorcycle.

Maybe I'll just pick up the 1/4 inch wrench for those smaller fasteners. Any excuse to buy more tools,lol!

Good and tight. Don’t spend $400 to torque 4 bolts

when i did my smog block offs, just a little blue loctite, snug down and call it a day

For that kind of stuff I just use a real short 1/4" drive ratchet and snug it down. But I have been doing it a loooong time and have a good feel for it. I am surprised at how many guys will break off small screws like that. If you try using even a normal 3/8 drive ratchet its hard to get a good feel for it because the handle is too long.

More critical stuff like on cylinder heads I will use the 1/4' drive torque wrench.

Usually accuracy is spec'd 20-100% full scale... for the techangle, I found a document that states:

20-100% FS: 2% CW, 3% CCW
10-19% FS: 4% CW, 6% CCW
5-9% FS: 8% CW, 10% CCW (TECH2 only)

I think a 1/4" beam style is going to be your best bet for that low torque. One of those shouldn't be very expensive.

Thanks guys, I will do as you recommend, a little LocTite, a 1/4 ratchet, and snug them up. Thanks

Unless you're dealing with something squishy that has no feel, you don't need a torque wrench. But for future reference at 7 foot pounds, an inch pound torque is best.

Insane to spend money on a torque wrench for that one time application.

I have the same Techangle wrench as you do, and I use it all the time, more than all my other torque wrenches added together, and yes, down to 10nm. I have compared it to my freshly calibrated 1/4" in/lb micrometer style at the lower end and to my 3/8" 15-75ft/lb micrometer style at 50ft/lb. I also use a pre-set 8nm t-handle on 6mm case cover bolts and then the TA to finish to 10nm and have complete confidence in it. I have been in the industry since the early 80's and I think it is my favorite tool ever!

What makes you think he got it for THAT application? I'm assuming he had some Torque To Yield bolts to tighten at some point is the reason why he bought it. I try to give people the benefit of the doubt.

I just checked their spec sheet. It is the same as the mechanical ones, Accuracy(3%) is from 100% to 20% of full scale. That means it is guaranteed to be in tolerance down to 20 ft lbs.Some wrenches, like this one, go below the usable range.

According to the manual for my ATECH2F100GB 5-100LB wrench;

+/- 2% accuracy (3% ccw) 20-100% of scale
+/- 4% accuracy (6%ccw) 10-19% of scale
+/- 8% accuracy (10%ccw) 5-9% of scale

The calibration certificate shows it was tested at 20lb, 60lb and 100lb, quite accurate as well.
