Product Description
Hex Washer Flange (HWF) Self-Drilling Screws
Product Description
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.

Applications
- Heavy structural steel connections
- Trailer and truck body manufacturing
- Agricultural equipment assembly
- Solar panel mounting systems
- Construction of industrial storage racks
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.
