Hex Flange Self-Tapping Screw with Leak-Proof Sealing Washer for Roof Tile Pads

Hex Flange Self-Tapping Screw with Leak-Proof Sealing Washer for Roof Tile Pads

Product Overview

Our Hex Flange Self-Tapping Screw with Leak-Proof Sealing Washer is engineered for secure, weatherproof fastening of roof tiles, panels, and outdoor cladding. Featuring a hex flange head for tool-driven installation, a self-tapping tip for effortless penetration into metal or wood substrates, and an EPDM sealing washer to block water ingress, this screw ensures long-term durability and leak-free performance in roofing applications. Ideal for contractors and builders, it combines strength, speed, and protection against harsh weather.

Key Features

✅ Hex Flange Head Design

  • Tool-Friendly Installation: Compatible with standard hex keys or sockets (e.g., 8mm, 10mm) for high-torque driving.
  • Integrated Washer Function: Flange distributes load to prevent surface damage and pull-through.

✅ Self-Tapping Sharp Point

  • No Pre-Drilling Required: Cuts through metal roof tiles, battens, or wood substrates effortlessly.
  • Coarse Threads: Aggressive grip for secure fastening in dynamic weather conditions.

✅ EPDM Sealing Washer

  • Leak-Proof Seal: UV-resistant EPDM rubber compresses to form a watertight barrier against rain, snow, and moisture.
  • Durable & Flexible: Withstands temperature extremes (-40°C to 120°C) without cracking.

✅ Corrosion-Resistant Construction

  • Material Options: A2/A4 stainless steel or zinc-plated carbon steel for rust-proof performance.
  • Roofing Compliance: Meets ASTM B633 and ISO 3506 standards for outdoor durability.
