What is the difference between
Bolt-on holds and Screw-on holds?
Bolt-on holds generally have one anchor point. They require
3/8" socket-head bolts and the installation of 3/8" T-nuts in the back
of the wall. Once the T-nuts are installed, fastening and removing the
holds is extremely easy. All you need is a 5/16 hex key/wrench.
Bolt-ons are best if you intend to move the holds and change the routes several times a year.

Screw-on holds always have at least 2 anchor points. The pre-cast holes
in each hold are 1/4" in diameter. We use 2" weather
resistant Deck Mate screws to fasten them to the wall. You will need a power
drill with a philips head bit to install and remove these holds.
Screw-ons are great for outdoor applications because they require almost zero maintainance to remain secure. If you do not intend to change hold positions and create new routes frequently, screw-ons are the way to go.
