BEST A4F3 – Frequently Asked Questions

1) Do BEST A4F system pins come as top pins or bottom pins, and what is the difference?
Both. The A4F pin kit is ordered by position: bottom pins, which sit against the key cuts and set the height, and top pins (drivers), which sit above them and load against the spring. Pick the position you are short of, since the two are not interchangeable in a pin stack. Each is packaged 100 to a polybag.
2) What pin sizes are available for BEST A4F cylinders?
A4F pins are sold by pin number, and the range runs 0 through 9, then 11, 12, 13, 14, 16, 18 and 19. Both the bottom pin and the top pin are offered across those numbers, so a pinning kit can be rebuilt one depth at a time rather than buying a full assortment.
3) Are BEST A4F pins the right ones for rekeying a BEST small format interchangeable core?
These are the BEST-manufactured pins for the A4F system, so they belong in BEST cylinders built to that system, not in a generic SFIC pinning kit from another maker. Confirm the core you are servicing is A4F before you load a stack, because pin numbering is only meaningful within its own system.
4) How many BEST A4F pins come in a bag, and is that enough for a rekey program?
Each bag holds 100 pins of a single number and position. For a locksmith or a facility maintenance shop pinning many cores to one masterkey system, that quantity covers repeat depths across a lot of cylinders; for a one-off core, it is more than a single job needs.
5) What else do I need besides pins to rebuild a BEST A4F core?
Pins alone will not finish the job. A pin stack also needs springs, and an interchangeable core rebuild needs the core shell, the control sleeve and the correct cut keys for the change and control functions. Order the springs and any shells separately; the polybag contains pins only, in the one number and position you select.
6) Can I mix BEST A4F pins with pins from another manufacturer in the same cylinder?
Don't. Pin diameters and depth increments are specific to the system they were made for, and mixing brands in one stack gives you a cylinder that binds or picks open. Keep the whole stack on A4F pins if the core is an A4F core.
