superb quality and amazing price
I broke several of these screws while creating a custom pickup. They're made of brass as to not interfere with the magnetic field of the pickup, But if you feel that you have to push and twist and force these screws into place, then DON'T! widen the screw holes a little first (2mm worked wonderfully for me). The good news is, once these guys are in place, they do what theyre supposed to do.
