Worked well for my project and sturdy

Good bolts, kind of what I needed. Half of the bolts won't go all the way into the cap nut, however, and leave about a 5 mm gap even when put through another die to clean any debris. I needed a pretty precise fit, so this didn't work out for my purposes. Otherwise, good finish and quality!

Excellent quality and as described.before purchasing I could not clearly understand what length of screw to get to clamp my item successfully. There is a range of clamping length that a screw and nut will give. This is not shown on the drawings.So after purchasing the mix pack, the following was found.The length of screw is given. This is the length of the screw from under the head of the screw.The length of the nut is 18 mm from under the head of the nut. Now the thread does not run the whole length of the nut hence the need to run the nut onto the screw to see the the minimum clamp length ie the minimum distance that the screw and nut will clamp down on.For a 40 mm screw has a minimum clamp length of 42mm. Round up to 43mm to allow error of measurement or sample differences.Allowing for a minimum of 6 thread engagement the maximum clamp length was 49 mm.So a 40mm screw will work from 44 mm to 49 mm. This gives a working range of 5mm.The working range will be the same for any length of screw.40mm screw will clamp from 44 to 49 mm50mm screw will clamp from 54 to 59 mmYou get the idea. One could add a millimeter onto the Maximum length and still be OK but I have not done this since I prefer 6 thread engagement rather that 4.5 to 5. since the door I am using theses on are very heavy.A quick way to convert Metric to imperial is to buy a cheap ruler with both and draw a line of the require length and measure in the preferred conversion, go to the web for a conversion table or buy a cheap vernier gauge with both metric and imperial markings.

These are nice thick furniture connecting screws. Make sure that they are the right size for your furniture that you are connecting.

If you’ve ever thought to yourself, “Wow, life is going too smoothly, I’d love to waste an afternoon cross-threading cheap hardware,” then congratulations—you’ve found your perfect product.These allen screws with cap nuts offer all the refinement of a gravel driveway. The threads are cut with such surgical precision that they seem to actively repel one another, like two cats being forced into a bathtub. Every turn of the allen key feels less like fastening and more like filing metal off both the screw and the nut at the same time.Thread engagement? Forget it. You’ll get halfway down and suddenly discover that the screw has decided to freestyle a brand-new set of threads—at a jaunty angle. It’s like watching a toddler draw with crayons: sure, it’s “technically threading,” but good luck making sense of it.In short: if you’re assembling something you care about, buy literally anything else. If you’re trying to invent new curse words while sweating over stripped screws and misaligned cap nuts, then these are perfect.

Too long for my project, but still put to good use.
