Boltsize-It Gauge, Blue

Bulky; needed to take measurement of a bolt on a bicycle and was not able to use this tool. The tool is too bulky and is difficult to use even in such basic situation as measuring size of a bolt on a kids bicycle. Was disappointed that could not use the tool.

As advertised. Shipped quickly. No more guessing the actual bolt sizes (Yes, the threaded part, not the head). Measures both Standard and Metric bolt diameter, length in inches and millimeter. Has a decent thread pitch guide on the back and measures nut sizes (standard only). Theyve managed to pack a lot on this little piece of plastic which is thick and durable hard plastic. I would totally recommend.

Excellent tool

Got this for quick and easy measurements, works great!!

The title says everything. What size is it? Look at it and use a thread pitch gage if need be, but dont screw yourself and the job. Get it right, do it right, and take pride in your mechanical repairs and avoid those unnecessary trips for the right fasteners.

Have you ever gone to the store to pick up those nuts, bolts and washers you need only to find you guessed wrong on the sizes. Well I have. Never do that again and know exactly what you have and/or need with this simple inexpensive tool.

This is great to find the right bolt, screw or nut for the repair or fabrication task at hand. I use this to replace a few broken cheaply made (china grade bolts) that came on some kids swing sets. With this tool, I was able to go to the hardware store and buy the right bolts (grade AA American made)

As advertised

I like this gauge because it is sturdy and easy to use. It saves me a lot of time. It does take a lot of guesswork out of sizing nuts and bolts

The male sizers on the side, along with the massive amount of female sizers ensure that everything will fit snugly. Size matters.
