Callaham saddles come fitted with 5/16" screws in the 1st and 6th position and 3/8" screws in the other positions which is standard for most saddle sets.

As part of the final fine adjustment if you find that too much of the screw is protruding or you may need longer screws to achieve the correct action

We offer 1/4" (6.3mm), 5/16" (8mm) and 3/8" (9.5mm) screws in sets of 2 which you can use to ensure that you get the correct adjustment with as little of the screws protruding as possible.
