Thank you for your order. You should receive the blocks with headless bolts in a couple of days.
The bolts are basically M10 slotted set screws that are 40mm long. 12mm of the length is threaded leaving a 28mm long pin to hold the blocks in place.
It's not necessary to drill the hole all the way through the saddle when using the headless bolts. It helps to have a drill press.
