Torque Wrenches. Interesting to some! - Julian Lindley
I notice that the "Teng" product has a patented angular facility on its units for use with bolts that are loaded by angle. Any views on this product? I have used an angular guage in the past, that can be fiddley depending on bolt location.

The Halfords item, a Norbar product, 60 - 300 Nm, does not have this facility but seems to have good accuracy, with a average error over 5 readings of:

@ 60 Nm +/- 1.69%

@ 180 Nm +/- 0.49%

@ 300 Nm +/- 0.32%

These figures derived from a copy of the calibration certificate.

I use a T wrench irregularly; my current unit is clapped out.

Regards,

Julian

I do know Norbar are good.

I ran over my torque wrench with a Land Rover: it still works, but I'm not sure how accurate it is any more....
Re: Torque Wrenches. Interesting to some! - Mike Wolstencroft
Though this sounds really 'anoraky', I hate 'em - they mostly measure the friction of the thread being screwed. Most accurate method is to measure the stretch of the bolt being tightened, using calipers, but this is impossible in most car situations eg cylinder head bolts. Bolt tighteneing sequence is probably more important anyway...
