Hex Washer Flange (HWF) self-drilling screws combine the functionality of a hex head screw with an integrated flange washer, creating a single-piece fastener solution. Designed for heavy-duty applications, these screws offer exceptional load-bearing capacity and vibration resistance. The flange washer eliminates the need for separate washers, simplifying inventory and installation while ensuring uniform load distribution across the joint surface.

Advantages
The integrated flange washer provides a larger bearing surface, distributing pressure evenly to prevent material deformation.
Eliminates the need for separate washers, reducing part count and installation time.
High torsional strength and case hardness ensure reliable performance in high-torque and vibration-prone environments.
The hex head design allows for secure engagement with standard tools, reducing the risk of slippage during installation.
Customizable finishes and sizes make these screws suitable for diverse industrial and construction applications.
Features
Integrated self-drilling point enables fast, clean penetration into metal substrates without pre-drilling.
The one-piece flange design provides superior resistance to loosening caused by vibration and thermal expansion/contraction.
Optimized thread design ensures strong grip in both thin and thick metal sheets, preventing pull-out.
Consistent heat treatment ensures uniform hardness across the screw, preventing premature failure.
The wide flange creates a weather-tight seal in roofing and cladding applications, enhancing water resistance.
