Painted Hex Washer Head (PHWH) Self-Drilling Screws
Product Description
Painted Hex Washer Head (PHWH) self-drilling screws are engineered for high-performance fastening in metal-to-metal and metal-to-wood applications. The painted finish provides superior corrosion resistance and color matching for various substrates, while the integrated hex washer head offers a large bearing surface for even load distribution. These screws eliminate the need for pre-drilling, streamlining installation and reducing labor time.
