90 Sets Chicago screws Assorted Kit 6 Sizes Silvery Leather Rivets 3/16(5mm)Screw Rivets Phillip Head Book Binding Posts Nail Rivet Chicago Bolts for DIY Leather Craft Bookbinding (5 x 4,5,6,8,10,12)

I bought these for leather notebooks, trays, etc. Having a variety of sizes is very helpful. The quality seems good, and the Phillips drive slots are deep enough that they won’t strip out. A nice product.

They work fine but not sure if they will vibrate loose or not there's no way to lock them in the Philips drive is real small.

While the picture shows 3 sizes they all use the same short screw. Because of that they are more likely to work loose. I had to go to the belt manufacturer and buy their screws to work.

The thread is of poor quality and cannot be screwed on.

Not sure what size I would need, these you can change any time.

Needs screwdriver slot on both pieces

Work just as good as the higher end ones. Received as described. Will definitely buy again.

Great for arts and crafts
