Received product as pictured but they were even nicer than I thought. Heavy duty, handy and easy to mount/hang in my workshop. Was working on wife's car over the weekend and the thread checkers were used many times making the job smooth and less stressful. Was able to find the right size bolt for the radiator with ease. Cool addition to my tool collection.

Très belle qualité de fabrication, très bien conçu, très pratique à utiliser. Avec du métrique et de l'impérial, des pas fins et larges, ce qui couvre la majeure partie des besoins. Par contre, chaque panneau est un peu plus étroit qu'une feuille A4, c'est très grand ! Pas facile à ranger, ni à transporter...

These are listed as an upgraded model with a heavier 5mm thick plate. The anodizing is perfectly done, and the laser markings are crisp and clear. The included standoffs keep the plates off the work surface and provide clearance to run a bolt through to check the thread size. The thick plate really gives these a high-quality feel. Perfect addition to the shop, mounted on the wall next to my mill.

Okay, so I'm not a professional mechanic or anything, but I am a DIY enthusiast, and let me tell you, I've spent WAY too much time in the past trying to figure out what size nut or bolt I needed. I'd be rummaging through my toolbox, holding up different fasteners, squinting, and just hoping for the best. More often than not, I'd end up making a trip to the hardware store again because I had the wrong size. Ugh! So frustrating! That's why I'm absolutely thrilled with this GIMYUAN Nut and Bolt Thread Checker. Seriously, it's been a lifesaver! It's so simple – just hold your nut or bolt up to the board, and BAM! You know exactly what size it is. It has both standard and metric sizes, which is perfect for me since I work on a mix of projects. Plus, it even has a drill bit gauge, which is a nice bonus. The bright red color makes it easy to spot in my cluttered workshop (let's be honest, who doesn't have a cluttered workshop?), and the fact that it mounts on the wall is super convenient. It keeps it out of the way but always within reach. No more digging through drawers! Honestly, this thread checker has saved me so much time and frustration. It's a well-made, sturdy tool, and it's so incredibly useful. If you're tired of guessing with nuts and bolts, do yourself a favor and grab one of these. You won't regret it! Five stars from me!

Der GIMYUAN 48 Gewindeprüfer beitet eine einfache Möglichkeit herauszufenden welche Schraube oder Mutter man hat oder braucht.Unser altes Haus kam mit einer menge an Schrauben und Muttern in Büchsen oder Tüten. Als Freund der Wiederverwendung suchte ich nach einer Möglichkeit diese schnell zu sortieren. Außerdem Schraube ich gerne an meinen Motorrädern und ersetze dabei die Originalschrauben durch neue mit besserer Qualität oder anderem Kopf.Deshalb kam mir die Möglichkeit über das Vine Programm das GIMYUAN 48 Gewindeprüfer zu erhalten gerade recht.In den beiden aus starkem rot anodierten Aluminium hergestellten Brettern befinden sich kurze Gewindestangen aus Stahl und mit Gewinde versehene Löcher die es einfach machen Durchmesser und Gewindetyp herauszufinden.An die Platten werden Kunstofffüse angeschraubt, die es ermöglich die Platte auch auf der Werkbank liegen zu verwenden. Löcher und Schlitze für die Möglichkeit zum Aufhängen an der Werkzeugwand sind ebenfalls vorhanden.Da ich in Deutschland lebe, war ich skeptisch ob ich die "Standard" Platte jemals brauchen würde, denn Standard ist hier nicht Metrisch, es ist inch. Mein erstes Projekt das ich nach dem erhalt der gewindeprüfer angefasst habe, hat mich jedoch eine besseren Belehrt. Das verwendete Gewinde war nicht metrisch.Mein Fazit:Auch wenn man es vermutlich nicht sehr oft braucht, wenn man wie ich Schrauben gern mal durch neue ersetzt oder alte wiederverwenden möchte, ist der GIMYUAN 48 Gewindeprüfer Set eine echte Hilfe.

This tool is about as cool as it gets when it comes to fasteners. I am so impressed with the way this was made from the rubber feet to protect my counter and keep it firmly in place to the quality of the engraving in the aluminum. This is a valuable tool when you (like me) have drawers of miscellaneous nuts and bolts and want to be able to sort them and actually put them to good use. With this, you can identify the thread and size of all of your nuts and bolts for organization and just to determine what you have and need for a project. I really like this tool.

Excellent tool to measure and identify metric and standard drill bits, nuts and bolts sizes. Simple to use, just thread on the nut or screw in the screw / bolt to measure the exact thread size. The aluminum plates are very nicely crafted and so easy to read. They are clearly marked and defined. Included are screwable feet for each board with a small screwdriver to assemble them. Using these gives you the choice of hanging these on a wall, or laying them flat on the workbench. This tool works well and is so cool to have in any household or job site. I have never owned one of these, and now I can never be without them.

Whether you work on the occasional project at home or are a handyman by trade, you've likely encountered those scenarios where you aren't sure what size bolt or nut you have or need to finish the job. Most everyone has that container or drawer full of random nuts and bolts saved from other projects or excess parts that came with an item. These thread checkers are the perfect solution to take out the guesswork and save you time and aggravation.The quality of these are outstanding. Using a combination of aluminum and steel, they are sturdy and quite durable. They are designed to be either wall mounted or placed on a table using the included rubber feet for stability. They have a good weight to them which lends itself to the overall quality and the expectation they will stand up to the test of time. The spacing on the larger bolt threads is wider than the smaller ones which should allow for adequate testing for virtually any nuts you are looking to test.I highly recommend this product if you are in need of a thread checker or find yourself constantly trying to figure out what size you need when it comes to nuts and bolts.

I've always wanted a nice nut/bolt checker like at the hardware store. I've had a few cheap ones, and they're fine...but this one BLEW ME AWAY.First of all, they are HUGE! I'm not sure what I expected, but they are each as big as a sheet of paper and weigh several pounds. You'll mount this on the wall, not toss it in your toolbox.The assortment of nut and bolt threads is impressive. Especially the big ones. I doubt I'll ever need to size a 22mm bolt...but I do, this will be my go-to.The drill sizer is a bonus. It only has a few sizes, so I'm not sure how much I'll use that. I can eye-ball the common drill sizes easy enough. But, it's just a few more holes in the board, so I'll take it!Build quality is top-notch and they are simply lovely to look at. The threads are well cut -- perfect, as far as I can tell. I tested a handful of sizes I had on my bench, and no surprise that they identified them correctly.All in all, I recommend this if you deal with larger bolts and nuts, or you just love gorgeous tools. If you are a mere mortal like me and a 1/2" bolt feels hefty in your hand, you might want to find something smaller that will cover 95% of what you'll ever need.
