| You'd be lucky to find a decent torque wrench that covers the whole range for a duc, bearing in mind those little 8mm jobbies just need a bit of a squeeze and that wheel nut takes more of a HEAVE. Snap-on do a rather lovely 20Nm - 100Nm which covers quite a lot. Pretty expensive though but you do get what you pay for and the vans often have "special offers" which can take some of the sting out. They also do a nice low scale (5Nm - 20Nm) wrench for small fasteners....you know the ones that get over tightened and the thread strips! Both are 3/8 drive which IMHO is best for bikey type stuff. |
