I bought this fan and it didn't come with any blade screws washers or any component to put it together need to know how many I need and what size and what I need to assemble this fan

You are asking questions related to the mechanical instructions. This is a forum that responds to electrical issues, not mechanical.

New fan? Take it back. Home Depot and Lowe's have blade screws. They come in various size and length.

These fans are rated very poorly by Consumers Reports. No customer service, unavailable replacement parts, Walmart quality.
