44pcs Nut and Bolt Thread Checker, 23 Inch & 21 Metric Box Set Thread Gauge, Thread Checker Standard and Metric Suitable for Size Checker of Bolts or Nuts in Narrow Areas

Definitely helpful to have around. Yes they have something similar at the hardware store but that does not always help you when you need to measure something at your house or cannot remove and take to the store to find the size. Have used many times, they quality and value are worth it. They have been accurate and the case is nice quality to keep them stored.

A great addition to your personal tool arsenal.

This one surprised me. It’s a great product. Come with both coarse and fine + SEA and Metric. Bought it to put my bolt organizer to use and it’s 10x easier than using a ruler or caliper or 4$ size board from Lowe’s. The product comes in a decent case that has 2 layers of foam (top and bottom) the pieces include some really small one but they fit in the foam tightly and won’t shake out. All pieces are actually made out of metal which surprised me.

Been wanting one of these, plan is to organize my multiple bolt/nut collection. I tested about a dozen different bolts/nuts so far. Easy to read sizes, all aluminum pieces...will need to be careful not to force/strip any...Only negative is price, IMO, pieces sit in foam, case is a nice addition but not worth the extra money for a set without a case. Pieces Do Not have holes for wire. Lost one star for price...

So far has worked out great. I often need to know what threads I have or am looking for and this set makes that much easier. Note they are made of aluminum so you just need to use care when checking a thread so as to not damage the pieces. I have not had any issues as I am accustom to machine parts and threading but I can see someone not careful damaging the test pieces. Its paid for itself almost right way. Good value as well. Also like the case and layout versus those on a cable or chain as easy to find what I am looking for. Yes maybe a little larger to transport but no issue in my shop. Also protects the test pieces as well.

This is a cool product with a wide variety of sizes. Must have for every garage. Was initially looking for a board like you see in ACE or Home Depot but this seems like a step above those

This kit has great quality. I did have to use adhesive to keep the top foam piece from falling out when I opened it. Super happy with it! Addendum 9/30/2024: I want to add, as one user pointed out, the text of the advertisement above incorrectly states that the material is carbon steel, which it is not. It is not magnetic and I would guess it is anodized aluminum. In any case, if used appropriately without excessive force, they have proven to be durable and allowed me to sort hundreds of SAE and metric nuts and bolts with no apparent wear. I still highly recommend them for general purpose use. They are not meant to be thread chasers.

This kit is very nice and convenient. I've used it multiple times since purchasing it as I am restoring a couple of Jeep CJs. Works well for bolts and nuts. Highly recommend.
