Slip-type torque screwdriver?

[Plasmatic]

I'm trying to cook up an ogre-proof solution for some fasteners on a very expensive piece of equipment that keep getting broken.

I'm looking for a slip-type torque screwdriver that can be set pretty low, about 5-10 in-oz (need to check the exact spec before buying...).

(I specify slip-type because I want to make it impossible for someone to ignore the click/dial reading and keep going...if you have other suggestions to obtain this level of fool-proofness, I would love to hear it!)


The key feature I haven't been able to find is that I want it to be able to put out at least twice as much torque when backing the screw out -- there isn't any harm in over-torquing when taking the screw out, and I don't want anyone to feel the need to get the bright idea of putting a non-torque-limited driver near the very expensive piece of equipment and its delicate screws.

Ideally it should accept 1/4" hex bits, but the screws have slotted drive, so I should be able to work with just about any system.

Anyone have recommendations of something that fits this bill? (And preferably doesn't break the bank...)

Several other styles available. The cam over action is what you're looking for.

we used these for some specialty printer work years back.

Thanks for the suggestions, I'll take a look at both of those!

The German made Rahsol Dremotec torque screwdrivers work exactly the way you describe. Really nicely made tools with colour coded anodised handles, good and durable, and not too costly. Think they make the torque screwdrivers for Gedore too, which you might find easier to obtain stateside!

I have to say though, that is sometimes hard to totally 'idiot proof' some of these jobs! You can give a guy a torque wrench, but unless you show him how to use it he'll click it half a dozen times, or put one bolt of four in a float chamber and torque it up before starting on the others, then wonder why it leaks!

Get a decent torque driver, and if you don't like any of the previous suggestions I'd be surprised if Norbar don't offer one, but take the trouble to not only tell your guys how to do the job, but SHOW them how, and tell them why!

Great suggestions all around, nothing more to add in that arena. 5 to 10 in.oz., that's some real light torque.
