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.

  5. Customizable lengths and finishes allow for tailored solutions to meet specific project requirements.
 

Features

 
  1. Integrated self-drilling point eliminates the need for pilot holes, saving time and labor costs.
  2. The hex washer head distributes clamping force evenly, reducing the risk of material damage.
  3. High torsional strength ensures reliable fastening under dynamic loads and vibration.
