Rely®⇒VP INDUSTRIES (Pcs-25) M3 Self Clinching nut Rivet Nut Round Head Steel Metal Sheet Mounting Hardware Fastener

Good finish and perfect size for most knock down furniture.

Quality is A-one.

If you get the measurements right, this is very useful. Quality looks good and I was able to fix my chairs

4/25 are defective.

Delivered item as shown on the website. The dowels are all uniform in length and diameter. The ends are cut at a conical angle. The dowels are serrated for excess glue to escape. Dowels are good for edge joining of boards where dowels are hidden. However if you are using them in a place where the dowel end(s) are visible, then the serration and the conical angle can be a problem. Even cutting off the conical end will still show the serrations. So in such cases a non serrated dowel may be better.

Avoid these. They are so flimsy that very first one broke while inserting into the wood plank with one half in the wood. Luckily I was still able to fix a nut but decided to use screws for the rest instead of the inserts. Can't even return them since it was past the return window.

Fortunately found this product which I couldn't get from hardware shops.Exact fit for my Cot and I could compensate at all missing locations during my shifting.Good product. Bit over priced, but that's fine.

Just see to your requirement and order correct size. This product is really nice. Awesome product, quality wise.
