Thread Checker, 34 Nut and Bolt Thread Checker Bolt Size, Identibolt 8 Drill Bit Gauge, Thread Gauge 19 Standard and 15 Metric Bolt and Nut Identifier Gauge with Inch and Centimeter Ruler

Needed this to help sort loose nuts and bolts that have just gathered in a magnetic tray. Definitely a great addition to any shop. Extremely well made and will help out when size is unknown. Just as pictured and highly recommend for the listed sizes.

I like this plate much better than the loops of free-floating pieces that can also be found. It is very well made, easy to read and can be hung on a wall. I've had no problem fitting large nuts on the large bolt studs. But YMMV depending on what you are measuring.

Easy to use. Like the available metric and standard sizing. Product is heavy duty.

This thread gauge takes all the guess work out of doing repair work. Now I can order the exact size nuts or bolts I need without having to order different sizes and guessing what replacement hardware I need. I wish I would've bought this sooner.

Very easy to access and use.

I use this in my shop all the time as most vehicles have metric and most my yard maintenance items are standard . This helps identify proper thread pitch .

Very helpful and makes going threw junk drawer so much faster

This would work for checking threads on bolts, however the studs are too close together to work for the bigger sizes of nuts. Pictures are attached so that you can see how the nut comes into contact with the ajacent studs before the nut threads onto the stud. Its a shame because it seems like it is well made, however that doesn't mean much if its poorly engineered. For $50 it'll be getting returned.
