post-gageit.jpgWe came across the Gage-It hardware gauge this week when we were at Home Depot picking up some fasteners.  It’s an 8″x4″ piece of plastic with cut holes and slots and printed markings to help you measure all kinds of fasteners, drills, rod, tube, pipe, etc. 

The top and bottom are covered with ruler markings — both metric and standard.  The triangular cut in the left measures steel, brass, copper, PVC, and CPVC pipe by size.  The fork-looking extrusions on the right size nuts by internal thread diameter, and the holes in the center measure and identify screws and bolts.  A scale printed just inside the nut gauges identifies finishing nails, and a the big slot running horisontally measurs drills, rods, tubes, and wires by outer diameter.  The V-shaped cut bends out to measure pipe and tube fitting sizes by internal diameter.  The back also features lumber sizing and conversion charts.

At 89 cents each, there’s really no reason for you not to have one of these kicking around in your toolbox.

(No link — we couldn’t find it online.  Looks like you’ll have to pick it up from the brick & mortar like we did.)

    What aisle did you find this in? I’ve looked all over my local Home Depot for one and was unable to find it.

  2. Sean says:

    We found this one in the same aisle as the tape measures. They were in a small bin attached to the front of a shelf.

    Ha! I just went looking for web sources for this thing, since I was going to submit it as a reader find. Looks like you’ve been there, done that! Yes, my Gage-It and a $2 plastic micrometer come in inordinately handy.

    I couldn’t find these at my local HD, but I found something like it at Rockler. Search for “Bolt Size It”

  6. Randy says:

    I’ve had one of these for a couple of years now. It was in the hardware area, near all the screws and nails. It is very handy for checking the sizes of screws, nails, drill bits, wires, nuts, etc. Highly recommended.

    Armour Technologies Inc.

    Gage-It Pro is available from McMaster-Carr (mcmaster.com) has both the standard for $2.43 and the Deluxe for $4.93. The deluxe one is a thin tough card 10-1/2″ x 3-1/2″ and does all the standard one does plus+++. Good tool!

    This is the best thing I have ever found! However,wish it would have come with a few simple instructions. Does anyone know how to use the compass scale and Degress on back?

    To Stan,
    Today I got my Gage-It gauge from Home Depot in Hercules, CA
    These are my own conclusions since there is no instructions on how to use it.
    1. Using the compass. The red marking “COMPASS” is the center (zero mark) of the circle. The red numbers to the right .5, 1, 1.5, and 2 represent the diameter of the circle expressed in half inch, one, one and a half and two inches.
    To draw a 2 inch (diameter) circle place a pin thru the zero mark and a pencil on the number 2. Draw the circle.

    2. Angle. Turn the template over and you will see the marking ANGLE. Connecting this point with 0°, 5°, 10° etc., gives you the angle in relation to 0°.

    Hope this helps
