Torque Down The Little Ones
By Eric Dykstra
For every nut, bolt, and fastener on your car or truck, the factory probably recommends a specific amount of torque to tighten it down to. Mac makes two models of adjustable 1/4″ torque screwdrivers — the TSM4-22 and the TSM16-88 — that measure torque from 4 to 22 in./lbs and from 16 to 88 in./lbs respectively. With these little guys you can torque down even delicate fasteners without winging it.
A window on the driver’s handle shows the amount of torque with an accuracy of ± 6%. You adjust the screwdriver to the desired torque setting with an allen wrench — once you’ve applied the desired amount of torque, the driver disengages. Contact a Mac dealer for prices and availability.

These must be pretty new. Tried the part #’s listed above at the MAC website and they’re nowhere to be found.

I have built a lot of cars without one…….
Is this really needed. Come on. How many Stereo installs ahve been done with out using torque specs.

I could find a use for this on bicycles. More and more components for those are coming with torque specs, and as the materials become more carbon and aluminium than steel I’d be happy to get it right rather than crunch something expensive.

Grainger has these…been around for a while now.
But then again, I’ve not seen a Mac truck in years.
