Hex Flange Head Self Drilling Screws

Product Description

Hex Flange Head Self Drilling Screws offer a combination of quick installation, strong fastening, and corrosion resistancemaking them ideal for both industrial and construction applications.

Key Benefits

Rapid installation: Eliminates the need for pre-drilling, reducing labor and installation time significantly.

Superior holding force: Hex head design allows more torque, resulting in firmer tightening and reduced risk of stripping.

Corrosion and weather resistance: Often available with zinc plating or specialized coatings, making them suitable for outdoor and moisture-prone environments.

Durable and reliable: Made from hardened or treated steel, ensuring long-term strength and wear resistance.

Waterproofing: Frequently paired with bonded washers (such as EPDM or PVC) for increased leak prevention in roofing and exterior uses.

Typical Applications

Metal-to-metal and metal-to-wood fastening in steel structures, roofing, wall panels, and curtain wall assemblies.

Fixing colored steel sheets to purlins, I-beams, channels, and structural supports in industrial buildings and warehouses.

Common in HVAC systems, electrical/plumbing installations, shipbuilding, container manufacturing, and refrigeration equipment.

Frequently used in roofing projects for secure, leak-proof fastening of metal, plastic, and fiberglass sheets, especially with appropriate washers.

Usage Details

Drill tip design: Self-drilling (Tek-type) points can directly penetrate steel, aluminum, or composite substrates without pilot holes.

Hex flange head: Facilitates easy installation using wrenches or nut drivers, providing even load distribution and minimizing potential for cam-out.

Washers: Integrated flange or optional bonded washers enhance waterproofing and vibration resistance, essential for exterior and roofing jobs.

Recommended for use in materials like thin gauge metals and steel up to prescribed thickness limits based on screw size and drill point type.
