10pcs M6 x 50mm Furniture Joint Connector Bolt & Cap Nut Kit - Hex Socket Screws Head (50mm)

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.

They work and a neat bonus job they perform is showing how unlevel your floor is

Had to cut them down a bit but they fit tight.

When I received them I was a bit worried because they are supposed to draw down to 34mm and turning them by hand only went down to 37.5mm. My project requires a 38mm span, (too close for comfort). I had to use Allen wrenches and force them to a smaller span. They went all the way to 34mm as they are supposed to, but only with some force at the end of travel.I haven't actually installed them yet, but once forced they seem to be OK.An update. 18 of the 20 worked just fine for my application. 2 of the female parts did not have good internal threads, I was unable to tighten them at all. They went together real easy.. too easy.. that's why they wouldn't tighten. I have submitted a note to the seller and waiting to hear back.2nd update: The supplier returned my inquiry regarding replacing just the 2 that were bad. It seems they can't just replace the 2 so they are sending me the whole package again. Their response was very good. I have upgraded to 4 stars since they are making good on the defective two.

These are marketed as stainless steel, they are not. All the cap nuts are rusted in the inside and the bag they came in is full of rust dust.

The quality corresponds to what was in the description

I welded together some angle iron, and ordered the beautiful 20mm 30 pcs. kit of this cap nut-kit.To make it clear I wanted to advise the DIY crowd—these are super super nice in finish and quality, Thick chrome and they go together like a German-clock. To be clear: The male part is 20mm and the female part is about that same size on all the kits. For a one inch thick project these worked perfect (had to tighten all the way down).If you are clasping together 25mm of product—It would require the 25mm kit and so on. But I would not order a bigger size if you are using for example; 30mm or so on—the 30mm probably clasps up to 43mms or so on...So in reviewFor 25mm use 20mm. For 30mm use 30mm, for 40mm use 40mm or 30 or 35.I hope that is not to confusing—but just remember the "mm" measurement is the "male" part of the nut-kit and the "female" part stays the same size...

Used to join DIY mutiple flat pack base cabinets from Lowes. Provides more professional, better joint (than wood screws) when joining two particleboard side walls (these cabinets are frameless, ie. have no solid wood frame). Also allows for disassembly if necessary vs. screwing into particleboard.
