Not bike but car My qualified main dealer tech friend fitted a new gasket on the old focus, despite me telling him the torques of 2 newtons outward on the first circle and 7 newtons on the second cycle outwards, he grabbed hold of a normal socket set and wrenched it. Result, cracked plastic rocker cover and new one from ford coming from Germany (yes I know there are cheaper second hand ones but no guarantee's it won't be damaged) So, aware I can do it myself and looking for a torque wrench, most seem to be 10/20 newtons and upwards. Have you used a low level (sub 10 nms) torque wrench and if so, any recommendations?
This is the one I use for pushbikes. Not the best quality but does the job. https://www.chainreactioncycles.com/mobile/x-tools-essential-torque-wrench-set/rp-prod155414

I've had the same two torque wrenches since for ever , both are made by Norbar , and both are excellent . The high range wrench goes from about 30 Nm to 240 Nm , and anything higher than that is very tight indeed . Example : Clutch center ( hub ) nut needs about 190 Nm ...... same for the alternator rotor nut The low range wrench goes from maybe 8 Nm to around 40 Nm Anything less than that , for me , I would describe as "snug " or about as tight as you get with gentle hand pressure using a small T-bar , or a screwdriver handle for sockets . Example : anything involving plastic parts , such as fairing screws into " well-nuts " The lowest value I ever saw specified in a Ducati manual was about 8 Nm and for comparison hydraulic bleed nipples are specified as 12 Nm
Now that really IS low . The only time I ever used something that low was in an electronics factory when large power transistors were screwed to aluminium heatsinks
For precision when tightening screws with preset torques of 1.0 to 5.0 Nm. 2 - 10-Nm torque wrench (got this one its the bees-knees)
I was at my dentist the other day getting an implant. He said we torque the titanium plug into the jawbone to 70 newtons.... I was thinking Scania wheel nuts and envisaged my skull cracking in two until he told me newton centimetres... Phew!!
https://www.rutlandcycling.com/accessories/tools/giant-shed-torque-wrench-tool_320393 I've used this one for a couple of years now. Great quality feel to it considering the price.
I don't know about you, but that tightening is the worst fucking sensation I have ever had in my life...
I have a Snap-On electric torque wrench. It wasn't cheap but it's great for low-value torque settings. I've been through a few low-range (sub 50Nm) torque wrenches and was never really happy with any of them. Either do it by feel or invest in an expensive tool...
I was looking in a factory manual for something else and I came across these low torque figures - Manifold screw ( vacuum take-off ) ..... 5 Nm Water hose clamps ..... 2.5 Nm That beats what I said in an earlier post about the lowest I've found . Anybody else seen any super-low torque specs from manuals ?
