No special tools are required for our hand-driven CONCEALoc Hidden Fasteners when using TimberTech® grooved planks — just a drill/driver. We provide a #1 square-drive bit with the screws and CONCEALoc clips. If using TimberTech solid planks, you will need to use a router fitted with TimberTech’s CONCEALoc router bit to create a groove at each joist. You can find details on how to install CONCEALoc in grooved and solid planks in this TimberTech CONCEALoc installation video. CONCEALoc Hidden Fasteners can also be installed with a pneumatic installation tool available through TigerClaw/FastenMaster. Hand-driven CONCEALoc fasteners are available in 100 sq. ft. and 1000 sq. ft. stainless steel screws and clips. Pneumatic fasteners are available in a 500 sq. ft. gun pail with stainless clips and collated carbon steel screws.
