Hexagon Flange Head Tapping Screws

Hexagon Flange Head Tapping Screws are high-performance self-tapping fasteners designed for efficient, reliable connections in sheet metal, plastic, and light-gauge materials. These screws feature an integrated flange that functions as a built-in washer, distributing clamping force over a larger surface area to prevent material damage and ensure a secure hold.

The self-tapping design enables these screws to cut their own mating threads as they are driven into pre-drilled or pre-punched holes, streamlining installation and eliminating the need for separate thread-tapping operations. This makes them particularly valuable in high-volume assembly environments and applications where speed and efficiency are critical.

Features & Benefits

Integrated Flange Design: The built-in flange acts as a washer, distributing tightening force evenly across a larger surface area. This reduces surface stress, prevents the screw head from embedding into softer materials, and eliminates the need for separate washers.

Strong Self-Tapping Performance: The screw's specially designed thread configuration allows it to cut or form its own internal threads as it is driven into the substrate. This ensures a tight, secure fit without pre-tapping operations.

Hexagon Head for High Torque: The hexagonal head enables installation with standard hex wrenches or socket drivers, allowing higher torque application compared to cross-recessed drive types. This ensures consistent seating and reliable fastening.

Enhanced Corrosion Resistance: Manufactured from galvanized or stainless steel with various surface treatment options, these screws provide excellent corrosion resistance for extended service life in diverse environments.

Versatile Surface Treatment Options: Available in multiple finishes including environmental protection color zinc, blue-white zinc, black zinc, nickel plating, hot-dip galvanizing, and Dacromet coating to suit different application requirements and environmental conditions.

Precision Thread Geometry: Thread taper and dimensional accuracy comply with applicable standards, ensuring consistent performance and compatibility with standard tooling.
