312 Piece Black Tapping Screw Assortment

Interior panels, under-hood brackets, and body work assembled with silver-finish screws always look like aftermarket repairs — black-finish tapping screws are how professional body work and trim assembly actually looks when the panel goes back on. This 312-piece assortment covers two black-finish tapping screw types — black E-coat flat washer head and black oxide oval head — in #8 and #10 diameters across the most-used lengths, pre-organized in an 18-hole plastic drawer.

The E-coat (electrocoat) finish on the flat washer head screws provides a uniform black polymer coating that bonds directly to the steel. E-coat has good corrosion resistance and consistent color, making it the right choice for exterior and under-hood applications where the finish needs to hold up over time. Black oxide on the oval head screws is a chemical conversion coating that creates a black magnetite surface layer. It offers moderate corrosion resistance and a matte appearance that blends well with interior panels and trim. Black oxide screws are a common OEM fastener type for interior body work and trim assembly across many vehicle platforms. The head style choice — flat washer head vs. oval head — follows the same logic as other tapping screw applications. Flat washer heads spread clamping load across a larger bearing surface, which is useful for thinner or softer panels. Oval heads countersink slightly and leave a low, smooth profile, which is the right choice for visible trim applications where appearance matters.
