Cutting to the chase, these are screws... black screws. They are probably not the exact size/pitch that would go on a vintage US made guitar being that these are metric screws, but they are sized appropriately and hold well. In short, they work.In addition to working well, they can really refresh the look of a guitar with corroded or stripped fasteners... the little details that make a guitar go from looking decent to great.Now with that said, the price isn't too impressive. Yes, they're stainless, or so it's claimed, but still... almost $9 for 10 2.5mm screws. That's bordering on the point at which I feel it might be a too much. In the end though, it's less than $9... not $900. Just seems a tad steep and I wish I could deduct 1/2 a star for it. Other than that, these seem to be good to go.
