Poor Man's Bob Knobs.
Makes tool-less collimation of Reflector Telescopes easy.
These knobs are a tight friction fit to 4mm bolts.
You will need 3 bolts to replace the grub screws that came with your telescope. Simply take one to the hardware store to find it's size. Allow for extra length as the grub screws are recessed in the secondary holder.
My 12" Skywatcher dob required 4 x 35 mm bolts
Replace one at a time to keep rough collimation.
