Traditionally climbing holds are bolted onto your wall using the t-nut method, which involves drilling many holes into your wall, then hammering in a threaded t-nut.  The other option, if the hold allows for this is to simply use screws and attach the holds anywhere on your wall.  

What's good about screw-on holds?

• they can go anywhere on your wall, not limited like traditional holds are
• close to the edge between angle changes
• in tight corners
• on aretes
• they don't require a t-nutted hole
• they don't require a bolt
• can be added to walls with thick texture on them

What's bad about screw-on holds?

• nothing
