20pcs M6 Furniture Joint Connector Bolt & Cap Nut Kit Use for Cot Bed Crib Bolts Hex Drive Socket Cap Bolts - Hex Socket Screws Head (30mm)

Good quality-as described! Made in China, but I’m not prepared to deal with Temu just yet, so I end up buying something made in China from a United States seller who delivers it to my daughter in England, so I can pick it up from her when I visit her, so I can make a tree house in Ireland for her children (our grandchildren) to play in when they visit us! So much for reducing the carbon footprint!

I've been building furniture by using off-the-shelf components in non-standard ways. These bolts were exactly what I needed to join several kitchen top cabinets together to become built-in bookshelves. They're not fancy but they do their jobs.

Finish is 4/5, function 4.5/5, value 5/5. Happy with the purchase. I’m using it to join 3d prints.

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!

This kit provided lots of options for projects. If you have a need to keep the exposed parts out of the way, these work great. I also liked how many sizes were included to keep things moving along. For the quantity, cost seemed reasonable too.

Just right. The lengths essential

Exactly what you need to attach heavy drawer slides.

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 mm 50mm screw will clamp from 54 to 59 mm You 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.

Muy buenos en su función y el material bien cumplen su cometido calidad y precio los recomiendo
