Self Tapping Screws Assortment Kit, Black Oxide 410 Stainless Steel Sheet Metal Screws, 325PCS - #8#10 Self Drilling Screws for Metal Plastic, Length 1/2" to 1-1/4", (Hex Washer Head and Wafer Head)

Self-tapping screws are made of 410 stainless steel with high hardness and tensile strength, so the screw won't break easily.

The surface is black oxidized to provide extra protection.

Our self-drilling screws have the 11 most commonly used sizes: #8x1/2", #8x5/8", #8x3/4", #8x1", #8x1-1/4", #8x1-1/2", #10x1/2", #10x5/8", #10x3/4", #10x1", #10x1-1/4".

We wanted the box delivered to be perfect, so we reinforced the box for sturdiness.

Each type of drill screw is placed in a grid and clearly labeled for ready access and storage.
