What size are your screws and allen keys?

For our rigid collars we use a 2mm Allen Key with an M4 (4mm), 0.7mm x 5mm cup point socket screw.

Our locking flexible collars (rope and chain) use a smaller .05" Allen Key with a 4-40 x 1/4" socket set screw.

Replacement key sets are available for both sizes.
