Black Phosphate Self-Tapping Screws

These 1-inch black phosphate coated screws are designed for fastening tasks where a self-drilling tip speeds up installation. The wafer head provides a low-profile finish that sits flush with the material surface. They suit tradespeople and DIYers needing a reliable bulk supply for metal or wood applications.

Black Phosphate Coating for Adhesion

The phosphate finish is formulated to improve paint and mud adhesion directly on the fastener head. This helps prevent coating failure at fixing points in finished walls or fabricated assemblies. It is a practical choice when the fastener will be covered by a subsequent surface layer.

100-Piece Bulk Pack for Continuous Work

Supplied in a bag of 100 pieces, the pack supports extended jobs without frequent reordering. The self-tapping threads cut their own mating threads in pre-drilled or thin gauge material. No separate drill bit is included, so the installer must provide a compatible Phillips driver.

Questions about this item

How does the 1" length work once the screw is driven into a real project?

The 1" length provides sufficient thread engagement for securing thin metal sheets or attaching hardware to wood studs in typical framing or repair tasks.

What does the self-tapping and drilling design mean for the installation process?

The self-tapping and drilling tip cuts its own pilot hole and forms matching threads, so you can drive the screw directly without a separate drill bit or tap.

What do I need to drive and mount these wafer-head screws?

A standard Phillips driver bit and a cordless drill or impact driver are all that is required to seat the wafer head flush against the workpiece.
