Hex Flange Head Drill-Point Screws with EPDM Washer
Hetai – Custom Fastener Manufacturer
Hetai manufactures Hex Flange Head Drill-Point Screws with EPDM Washers, combining reliable drilling performance, secure fastening, and excellent sealing in a single fastener. Designed for metal-to-metal and metal-to-profile applications, these screws are an ideal solution for doors and windows, roofing systems, aluminum profiles, and other construction applications.
Integrated Drilling & Sealing Solution
The precision-formed drill point enables the screw to penetrate metal substrates efficiently without requiring a separate pilot hole in many applications. The hex flange head provides a large bearing surface and allows secure tightening with a hex socket or nut driver.
An integrated EPDM washer provides reliable sealing around the fastening point, helping prevent water penetration, moisture ingress, and corrosion caused by exposed fastening holes.
Designed for Doors, Windows & Metal Structures
These drill-point screws are particularly suitable for:
- Aluminum doors and windows
- Steel and aluminum profiles
- Roofing and cladding systems
- Metal sheets and panels
- Curtain wall systems
- HVAC and sheet-metal assemblies
- General construction and industrial applications
The combination of a flange head and EPDM sealing washer makes them especially useful where both mechanical fastening and weather resistance are required.
Custom Manufacturing by Hetai
As an experienced custom fastener manufacturer, Hetai can manufacture these screws according to customer drawings, samples, specifications, and application requirements.
Customization options include:
- Screw diameter and length
- Drill-point geometry
- Head dimensions
