i have a Jackson Fustion std with a schaller floyd rose that i replaced the saddles to that were jammed and my saddles started to slip from being old and rusty, so i found these which are hard to find and NO MORE SLIPING! dunno what the world would be like without a co. like stuart because they have all the little things you need to fix whatever you need without buying the whole new part!
Stewmac.com have excellent spare parts to the Floyd Rose Original. I'm impressed of the quality and the finish of the screws.
I have a washburn N4, 2006, the saddle screws that came on the Schaller are horrible. Very small hex, can't get them tight enough to really hold things down. I got these and wow what a difference, I am confident those saddles are not moving. Got the Allen wrench with them of course.
Replaced some worn out screws in a Washburn Licensed Floyd, definitely an upgrade. I feel like I can he-man these screws without breaking them, they are high quality.
