Open Ended Spanner Torque Wrench

This is what I got for that purpose: https://www.amazon.co.uk/gp/product/B0039UPTVI

 

What torque do they need? I did up a Swingarm adjuster nut today the torque was 6Nm, so I did it up till I felt it resist a little then a tiny bit more. 20NM would be tightened till you get tension then 1/2 a turn.

Tighten a nut in a vice to the torque setting requested then you get a feel for the force required.

Disclaimer ;- I cant say this is safe, so dont do it. Just me having a laugh.

 

Caution folks, most Torque wrenches that use spanner ends can have them fitted onto the torque tube [the torque wrench has no torque head] to be precise because as you move away from the centre line of the torque head it involves a re calculation

 

In the habit of looking up and using the correct torque specs on all the hardware, even the screws the hold the switch housings together. Had enough of the "dumb look on my face" when threads let go.

 

I also have one of these made by Torqueleader. Cracking piece of kit but only for delicate jobs or to avoid expensive mistakes

As in the example DD states, you have a £2k plus rifle scope and the bolts clamp this in place. Recoil tries to accelerate the gun backwards away from anything attached to it. Due to the amplification of distance ANY movement can lead to massive errors which could have secondary consequences.
The answer by most us to rive them down to be safe
The tiny screws either round out or shear off umm
Later, possibly quite some time later you remove the scope to find some (not) nice clamping bands perfectly formed in your expensive scope now not only crimping the tube but inevitably spoiling the future value as its damaged and the future clamping force is now inferior due to its reduced diameter.

Assess the job accurately BEFORE starting anything!

At the right time feel is good enough but at others it is foolish. Dont forget experience comes from making mistakes

In all I have 5 torque setting devices and although rarely used when they are needed it is usually imperative to do so.

 

I've got a couple of lovely Snap-On torque wrenches. I sometimes take them out of their boxes and look at them, they are very nice!
