I lost the screws for my drain for tile. What sizes do I need?

All the screws that come with the drain for tile are stainless steel, and they are metric sizes and thread counts. These are available at many well-stocked hardware stores in their specialty fastener section (often you'll find an aisle with pull-out drawers, and inside the drawers are all kinds of unique fasteners). Here is the screw information:

1. For the four screws that fasten the adaptor to the foundation, you really can use flat head screws that fit, and they don't have to be metric. We recommend #6 or #8 x 3/4" long, flathead, wood threaded style screws in stainless steel or ceramic coated. Always drill pilot holes before driving these screws.

2. To secure the clamping ring, you'll need M4 x 0.7 x 16mm long stainless steel screws. These have to be metric and the proper size and threading to fit the threaded holes in the adaptor.
