Thread Checker, Rustproof Nut and Bolt Thread Checker, Wall-Mountable Bolt Size Finder Tool, 15 SAE & 15 Metric Thread Gauge, Bolt and Nut Sizer for Quick Measurement

If you work with a lot of loose nuts and bolts, this is a really nice helper for organizing them. It is well-made, and based on the nuts and bolts I've sized, it is accurate. I have mine hung behind a cabinet door in my garage workshop, so it is readily accessible. Having priced out others, I believe this is a good value. Of course, it covers a lot of sizes, but not all possible sizes, but most of the common ones.

Very nicely made and good price. Plate is a little thin for the length of the female threads but perfectly sufficient.

This device is well made and easy to use. The construction is rugged and it is surprisingly heavy even though the base is aluminum. There are two rows of male and female fixtures. The left side is metric and the right side is Imperial. I found it was easiest to start with the male fixture for sorting both nuts and bolts. To sort nuts just try threading the nut onto each male fixture to see which one is a match. For bolts and screws it is easiest to start by visually checking which male piece is a near match by aligning the threads as shown in the photo. Then a final check can be made by screwing the bolt into the corresponding female opening. This is a fast way to match bolts, and it minimizes the risk of cross threading a bolt into the softer aluminum section. This worked great for sorting my junk drawer of miscellaneous nuts and bolts.

This is high quality and precise, and makes life a lot easier when I'm wrenching on something. No more guessing what size a nut or bolt is. Each gauge unscrews from the base so you can use them to check bolts/holes on things you can't pick up (like my garage door).

I would say a little “ overkill “ for a DIY’r but super nice ! Makes identifying threads easier. Very well built. Probably outlast me and my son!

Much better than I expected. Quality manufacturing with nicely finished threads. I will only use it occasionally so anticipate long life even though they're aluminum.

This will be so handy with both SAE & metric sizes. A Nicely made all metal device [not plastic]. It's already solved an irritating nut problem. A tiny 6-32 dillemia quickly & easily rectified for a porch light cover. Brass knurled nuts promptly acquired & installed.

Well-designed and sturdily made, it has just the right comination of sizes for a home workshop. Very happy with the purchase.
