8 x 1-1/4 Hex Washer SDS

Overview The 8 x 1-1/4 Hex Washer SDS (03285) is designed for self-drilling fastening applications in light gauge sheet metal and related construction assemblies. Manufactured by Midwest Fastener, this tek screw eliminates the need for a pilot hole by integrating a drill-shaped point that cuts through the substrate during installation, streamlining the fastening process on the job site. Technical Specifications MPN 03285 Brand Midwest Fastener Size #8 x 1-1/4 Head Style Hex Washer Point Type Self-Drilling (SDS / Tek) Category Hardware Fasteners > Screws Technical Features Self-drilling point geometry: The drill-shaped tip cuts through the substrate on contact, eliminating the need for a separate pilot hole and reducing installation steps. Hex washer head design: Provides a broad bearing surface that distributes clamping load across the fastened material, reducing the risk of pull-through on thin gauge substrates. #8 x 1-1/4 sizing: A compact screw length suited for light gauge sheet metal assemblies where material stack-up is minimal and a flush, secure finish is required. Tek screw construction: Functions similarly to a sheet metal screw but with the added self-drilling capability, making it compatible with standard hex-drive power tools for rapid installation. Applications Light gauge sheet metal fastening in construction and fabrication work Awning installation and frame assembly Door and window frame attachment Gutter installation and repair Shed construction and metal panel fastening
