New Allparts Schaller style Locking Tuning Keys, 6-in-line, Gold, with hardware, 18:1, lock knob on back- Includes Screws & Bushings. 

They fit modern 10mm tuner holes.

They do not fit vintage 8.8mm peg holes with press-in bushings.

These are excellent tuners, I have used these on many of my Strats and Tele's. The 18:1 ratio is great for fine tuning.
