Digital Torque wrench
« on: June 13, 2024, 12:52:43 PM »
Does anyone have any recommendation for such?
My smaller torque wrench is very difficult to read and also the scale of adjustment is impossible to judge. So my thoughts are to do digital. (3/8" or 1/2"  - not sure. )
I was pondering if the adapters that go between a ratchet and the socket may do.

I find a 3/8" torque wrench enough for our old bikes.

Digital would be a good idea, save me wearing reading spectacles to see the manual setting on my standard torque wrench.


I'll follow this thread and see what folk recommend...

I've never used a digital Torque wrench - I've avoided them as I am not sure how reliable they are if you drop it for instance?
Do they go rusty internally in a garage over the winter?
Can they be calibrated or checked?
Do do get a digital click or something to tell you it's reached the right setting?

I have a Britool 1/2 drive Torque wrench that was new in around 1975 - it's still working (range too high for Hondas) - I had the calibration checked about 25 years ago - it had a new spring fitted - I always release the tension after use. I used it when changing wheels - in old age I started using a set or Torque sticks instead!

You can calibrate yourself with a spring balance

Like the look of the digital torque gadget, although I have two wrenches already I hardly/occasionaly use. I remember the technical advisor to the AJS and Matchless owners clubs advice relating to getting the cylinder head tightened up which was by using the torque settings as a base point, followed if necessary by a little more and a little more then a little more until you think you are going to strip the threads then stop just before that happens!😳

Thanks for that Ash. I think I'm going to buy the 3/8th version and see how it goes. Mind you, my only issue is with the lower torques, so maybe the 1/4" drive would be best....

I've got a Sealey 1/4" drive torque wrench, not digital, and can do a lot of the engine work with that. I use a 3/8" drive one for the bigger values.

I got the 1/4" drive and low torque capacity mainly because I really wanted it for torquing M6 fasteners and big end bolts. I already had a larger 'Norbar' type clicking torque wrench that covers the higher torque settings on the chassis parts.

If the engine is in the frame for 500/550 don't think there is no room to get a digital gauge in place for the central four head nuts.
