Installation
- Simpson Strong-Tie Weatherboard Screws shall be installed into the weatherboards using the Simpson Strong-Tie Quik-Drive auto-feed screwdriving system.
- The Weatherboard Screws feature self-drilling tips, box threads and a trim-head profile which facilitate the screws being installed into weatherboards without the need for pre-drilling in most instances.
- Once you’ve got your boards tacked in place mark out your stud line and fixing height, or if your height is the standard 42mm from the bottom of the board, attach an accessory clip at the bottom of board and it’ll set it for you.
- All screws shall be overdriven to countersink the screw heads into the weatherboards sufficiently to allow for overfilling with exterior grade wood filler. Check with the board manufacturers specs, for most it’s around 3mm.
