I also use these shorter bezel screws to mount control cavity covers and most pickguards. I think they look classier than the larger Fender-style. Be sure to wax them before driving them in.

First place I turn to for my guitar parts

always correct

bought these to replace all the chrome on my guitsr. Counter sunk heads look even better. Slightly thinner than previous screws

Trying to use these on a Les Paul (P90 to humbucker conversion). Even after drilling a hole and turning the screw very slowly, I've stripped 2 and broken 3, one of which got stuck in the wood and I had to dig it out ,leaving a divot in the wood (fortunately won't be visible under the pickup ring). And that's all on the same hole. Guess I need a bigger drill bit.
I wanted to give them 1 star but I'll bump it to 2 because I think they will work with a bigger hole.

I got a bunch of them!

they are Humbucker Mounting Ring Screws,!,, good to have extras for when you go all Hendrix and burn the face of your guitar off

they fit my pickup rings perfectly!

Replaced the pick up trim rings on my Les Paul custom along with all mounting screws. These screws are fine with light pressure. 2 of the heads stripped out on the screws that needed to be driven a little deeper at the neck pickup. The rest were no issue.

I am in the process of building a guitar from a kit purchased from Stewmac. I wanted to change some parts, including humbucker rings and switch plate from ivory to black. In doing so, I ordered the parts from Stewmac and these parts did what I wanted. Worked great. Now I have just what I wanted for my new guitar.
