Hex Head SDS Self Drilling Screw

Product Description

Hex Head SDS (Self Drilling Screw) fasteners are engineered for secure, high-speed installation in metal, wood, and composite materials without the need for pre-drilling, making them ideal for structural, industrial, and roofing applications where maximum torque, efficiency, and corrosion resistance are required.

Key Benefits

Fast installation and reduced labor costs due to the self-drilling tip, eliminating pre-drilling steps and minimizing installation errors.

High torque application and secure grip provided by the hex head design, delivering a durable, tight bond even in heavy-duty environments.

Excellent corrosion resistance offered by stainless steel and zinc-plated variants, ensuring long-term durability for outdoor and moist conditions.

Versatility across material typesmetal, wood, compositeand a range of industrial and construction projects.

High pull-out strength and robust structural performance, especially with EPDM washers for leak-proof fixing in roofing contexts.

Typical Application

Structural steel assembly, metal and wood framing for industrial machinery, and large-scale construction sites.

Roofing and cladding installation, especially for fastening sheets to metal or wood frames, benefiting from EPDM washers for water protection.

Fastening brackets, components, and sheet goods in fabrication shops, hardware fitting, and pre-engineered building frameworks.

Used in projects involving high vibration and heavy loads due to their robust design and secure installation.

Usage & Installation Steps

Compatible with standard hex drivers and SDS (Slotted Drive System) tools for quick, efficient fastening.

Available in a wide range of sizes (M4-M10, #6-#14, lengths up to 150mm) and finishes (zinc plating, stainless steel, black oxide) to suit diverse project requirements.

Installation is straightforward: the screw drills and taps its own thread, reducing risk of misalignment and speeding up workflowespecially valuable in projects with repetitive tasks or limited time.
