armstrong-tsd.jpgThere’s no reason DIY projects can’t achieve the same level of professionalism as that of the biggest manufacturers — assuming the DIY-er brings a bit of skill and the right tools for the job.  In the case of some of the newer electronic projects such as robotics — a subject that has always fascinated us — properly torqued screws are the order of the day.  A 1/4″-drive torque screwdriver, like this one from Armstrong Tools, can help get you get the most out of those tricky fasteners on your next project.

Torque screwdrivers work much like torque wrenches; They just use the twisting motion of a screw driver instead of a socketed wrench.  They produce a crisp, audible click over the entire torque range so the user can hear when proper force has been applied.  A detent-style locking collar allows you to set the desired torque and prevents accidental changes in settings when in use.

A linear ball-bearing mechanism assures accuracy and repeatability of the settings by eliminating friction between the spring and case and provides a precise application to the user of between 6 and 36 in-lbs of torque.

This particular driver from Armstrong comes with a 1/4″-drive female hex adapter and is available on the web for around $165.  Yeah, that’s expensive if you’re just putting the vacuum cleaner back together, but if you’re assembling more mission-critical stuff (especially with stretch-type fasteners), you’re going to need one.

One Response to Armstrong’s 1/4″ Torque Screwdriver

  1. I would really like to see a precision (i.e., small) ratchet torque wrench, instead of a screwdriver. The twisting motion of the wrist is fine, up to a certain # of pounds. All the ratchets I have seen at Sears, Lowes, Harbor & Northern Freight are way to large. Also, the correct bit sizes to match the screw/bolt head is just as important.
