The sizes on the foam correspond directly to the individual thread gauges, allowing you to quickly identify, match, and select the correct gauge when you only need one at a time.
  • Quick Identification and Time Saver: Simply screw the nut or bolt onto the thread gauge to check the size in just seconds. With the JoblikeBrez thread checker for both standard and metric sizes, you can easily and quickly identify the correct size of nuts and bolts, making it simple to replace broken, loose, rusted, or old ones at home or in your garage. This eliminates the need for trips to the hardware store, significantly boosting your work efficiency.
  • Stay Organized: This nut and bolt organizer includes 66 male and female thread gauges, covering the most commonly used sizes for everyday tasks. It helps you quickly sort and organize mixed nuts and bolts with ease. This portable thread measuring tool is ideal not only for mechanics, electricians, engineers, and pipefitters working on mechanical projects but also for various home improvement tasks.

  • Look no further for an excellent kit!
Size: 60PCS Thread Checker Color: Red
This is fantastic. There are a lot of choices and I listed every size that each set came with and this checked off more metric sizes than others that I was looking at. There is always a chance though that it won't have the one I need but I feel pretty good about my choice. It's nice and small and appears to be well built. I have another set that is on a metal plank but it's not as versatile as this set it. The versatility was important to me and the value of the kit was excellent. It was so easy to pull out the piece and check the size of a bolt. They are very light and look to be made from aluminum. I give it 2 thumbs up! ... show more

  • Great tool!
Size: 30 Thread Checker Color: Red
This is a must have item for DIYers! Makes finding bolt/nut sizes easy and accurate. It’s well made and is a great value for the money! East to use and read. It’s light weight and fits well in a toolbox drawer.

  • Very Nice and Handy!
Size: 76 Thread Checker Color: Red
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. ... show more

  • This is a fine addition to my tools.
Size: 30 Thread Checker Color: Red
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.

  • Valuable tool
This helped me organize a bucket of random hardware. Accurate and well-labelled. Some of the threads feel weak so be careful with dirty bolts and don't use too much force.
