It depends... many spars, both booms and masts are too thin-walled to properly support a cheek block safely using screws and tapped holes. In cases like that, you may want to mount the cheek block to a mounting plate that is fastened to the boom.
For instance, on my friend's boat, we made up aluminum mounting bases for the line clutches, which were pop riveted to the mast. She then through bolted the line clutches to the mounting plates. The line clutches are removable for maintenance, but the bases create a solid and reliable connection between the line clutch and mast...and allow the line clutches to lead fair to the winches and exit slots.
For my halyards led aft project, I'm having three stainless steel plates made up that attach to the mast step base plate, and the turning blocks will mount to these three plates.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
