Check the specs on the digital readout T. wrenchews carefully -- I think you will see that they are NOT more accurate (i.e have greater resolution) and that it is just a gizmo for sales.

Oh yeh -- one other item -- torque is not a very good index of fastener strain. Really critical bolts (e.g. rod bolts) often use a different way to tighten to a given strain level.

OTOH, folks often use torque wrenches when they are not needed -- drain plugs and such for example. Get rid of your iron wrist and you won't need to torque nearly as many fasteners.

Randywebb is correct in saying torque is not a good indicator for a fastener. it is just the simplest to measure, but is also the easiest to vary (quantity of lube, dirt in bolt holes, etc) any members that need to be bolted together only really cares about the tension in the bolt. someone smart along time ago figured the torque required to meet the needed tension.

torque wrench

Valve covers are either 6 or 8 ft-lbs.
Rear axel nuts are 218 ft-lbs from memory.( Needed for rear bearing R&R)

I have a 0-150 ft-lb that doesn't fit either job. It is not accurate or small enough for the valve cover nuts so I use a fish scale on a modified ratchet.

I might look for a 10-250 ft-lb and then another one for the small stuff.

I thing clickers are more accurate than reading the pointer on a beam especially when working on the car.

I have three clickers:

1-25 lbs
10-75 lbs
25-150 lbs

For anything more (like 250 lbs), i stand on a bathroom scale and measure the torque that way.
