Boltsize-It Gauge, Blue

Brought for my hubby, he loves it.

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.

As advertised

This thing is rock solid hard plastic. Clear markings and easy to use. Better than I expected actually. Need to buy a second one for work now.

Easy to use

Choose another design. Bolt diameter part is OK but thread guage is horrible design; it is on the back so if it ends up in a drawer it will rub down or distort; needs better thread guage.

I keep a large assortment of fastening hardware (not all of which has been sorted...) and have found this gauge to be indispensable. It can be a real pain to try to find a screw or nut of just a certain size without it. It is of a simple go/no-go design making it easy to use. It is another product from Rockler and is made from a heavy gauge plastic which seems to be pretty durable.

I dont know what I did or how I made out before getting this. Used every day. Real Godsend

I use it often to check bolts and drills

I didnt find this plastic gauge useful, particularly the thread measure was hard to use accurately.
