Set of 6 in line, oval buttons, closed-type, 1 : 15 ratio, complete with washers and screws. This is a high quality product, with a perfect chrome finish. I used them to replace my Squier Bullet Strat tuners, and needed to enlarge the headstock holes with a tapered reamer hand tool (Squier tuner is 7-8 mm, Kluson are 10 mm). I also needed to fill one of the two screw holes of the Squire tuners, but the second hole fits the Kluson single hole peg - so no need to drill new holes. Very happy about this upgrade. By the way, the Bullet Strat is an excellent guitar, worth much more of its price.
