The appropriate screws for interior applications are as follows:
- 1¼" #8 Phillips flathead screws-to secure riser & treads to EZ Stairs bracket.
- 2½" #8 screws-2 per tread for each 9” of stair width.
For top screwing of treads only: 2" #12 sheet metal screws-6 per tread
Quick Time Saving Assembly tip:
Determine before you start your stair project exactly how many steps you need and how wide you want your steps to span. Pre-cut all risers and treads to those desired measurements. The only cuts that will need to be made will be the end cuts on both stringers… 6-8 cuts will be all that’s required for both customized stringers!
Also, pre-paint/stringers, treads and risers before you begin. Only minor touch-ups will be required.
