Product Description

Dacromet Hex Washer Head Self Drilling Screw With EPDM Washer

Product Details

These Dacromet-coated self-drilling screws are high-performance fasteners engineered for exceptional corrosion resistance, validated by 1000-hour salt spray test compliance (per ASTM B117 standards).

Key Features

Dacromet Coating: A pollution-free, inorganic ceramic coating (composed of zinc/aluminum flakes in a chromium-based matrix) that forms a dense, self-repairing protective barrier. Unlike traditional plating, it avoids hydrogen embrittlement (critical for high-strength applications) and resists solvents, gasoline, and extreme temperatures (up to 300°C/572°F).
1000-Hour Salt Spray Resistance: The coating delivers 7-10x better corrosion protection than standard zinc plating, enduring 1000+ hours of neutral salt spray exposure without red rust--ideal for marine, coastal, or outdoor environments.
Self-Drilling Design: Integrates a sharp, drill-point tip to eliminate pre-drilling, enabling fast installation in metal, wood, or composite materials (paired with a bonded washer for enhanced sealing in roofing/construction uses).
