Swpeet141Pcs 14 Different Sizes M6x16mm-80mm Carbon Steel Black Hex Drive Socket Cap Bolts Barrel Nuts Kit with 1Pcs Allen Wrench, Screw Post Fit for Furniture Countsunk Belt Leather Binding Bolts

The bolt and barrel nut are good quality. Still, here's what I wish I knew before I bought them:The EFFECTIVE BINDING DEPTH between the insides of the end caps is not the length of the bolt but is about 6mm-12mm larger (after four full nut turns which I believe is adequate to hold my table's legs to its frame). That is likely valid for the longer length bolts, too.The DEPTH BETWEEN THE BARREL AND ITS END CAP which holds the wood is only 2mm. Therefore, drilling to accommodate the barrel requires careful measuring for depth and diameter.At the time that I purchased these, they were less expensive than carriage bolts, washers+nuts.For my next project--yea, I survived this one, so far, anyway--I may consider buying this product to install the bolt from the outside but instead of using the provided barrel nut, tighten down a washer+nut, a flange nut or a wingnut.

Lucky for me i ordered steel bolts not the case it came in. people dont realize what happens to thin cheap plastic in cold freezing climates. It becomes brittle like glass. so when it was delivered and tossed on my doorstep the case shattered sending the contents all over the bag. bolts are ok.

Bought these for attaching handles on knives. About half of them work great the other half is slightly too large. I expected that but wanted to see the various sizes.Quality seems very nice, they are smooth, go together without any friction and are nice and heavy. (Yes they are metal, but they seem heavier than they should be)

Just what was needed to hold my bookcases together for a much nicer appearance! Used on IKEA Billy bookcases.

Dont buy for anything serious, maybe for ... actually I can't think of any use case.

Cheaper and better then stock parts. Works holding things better then stock part way!

The M6x35mm cap / barrel kit arrived on November 12, well ahead of schedule. They will be used to join IKEA Billy bookcases together.
