Muy buen producto

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.

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.

Not only is this a beautiful looking tool hanging on my shop wall, it works great, it takes no time at all for me to figure out if something is metric or SAE and what the thread pitch and bolt size is. I really don’t know why I waited so long to buy something like this. It’s way better than all of the other ones I have
