These are incredibly strong, yet light. Perfectly cut threads and a beautiful consistent finish. I use these on my custom built guitars where nothing but the best quality makes it on a build. Hex heads are closer tolerance than anything I've found out there. So snug. I won't use anything else. Just buy them.

Great Product.
