Hex Washer Head Self-Tapping Screws

Hex Washer Head Self-Tapping Screws are designed for fastening applications involving metal sheets, wood and other suitable construction materials. Featuring a hexagonal washer head and a tapered self-tapping point, these screws provide convenient installation and reliable fastening performance.

The hex washer head offers a wide bearing surface and allows easy installation using suitable socket drivers. The self-tapping point helps form mating threads during installation, while the coarse thread design provides effective engagement with compatible materials.

Available in carbon steel and stainless steel, with multiple surface finish options, these screws are widely used in metal roofing, construction, sheet metal fastening and general building applications.

Optional bonded EPDM sealing washers are available for applications requiring weather-resistant sealing.

The hexagonal head provides a secure contact surface for socket drivers, helping improve installation efficiency. The integrated washer-style flange distributes clamping force over a wider area.

2. Self-Tapping Point

The tapered self-tapping point helps the screw form threads in suitable materials during installation. Depending on the substrate and application, pre-drilling may be required.

3. Multiple Point Configurations

Available with different point designs, including Tapping Point, Spoon Point and Type #17, to accommodate different fastening requirements.

4. Multiple Material Options

Available in carbon steel and stainless steel grades 304, 316 and 410 to meet different application and material requirements.

5. Various Surface Finishes

Available with white zinc plating, yellow zinc plating, hot-dip galvanizing and Ruspert coating, depending on the selected product specification.

6. Optional EPDM Sealing Washer

Available with a bonded EPDM sealing washer to help provide a weather-resistant seal around the fastening point in suitable roofing and outdoor applications.

Hex Washer Head Self-Tapping Screws are suitable for a wide range of construction and fastening applications.
