8mm x 1 1/4" Self Drilling - Per Pkt

This screw is versatile for attaching metal to wood, sheet metal to metal, and drywall to metal. Its self-drilling tip eliminates the need for a pilot hole, making it efficient for quick assemblies and strong holds in thick or tough materials.

Key specs include a 8 mm diameter and 1 1/4" length, manufactured from hardened steel for durability, corrosion resistance for outdoor use, a built-in drill point for fast penetration, and a low-profile head for a neat, professional finish.

The item is sold per package with multiple pieces. Pack quantities vary, but these bulk-friendly packs are designed to support large or ongoing projects without frequent reordering.

Align the parts, start driving with an appropriate driver bit for the screw head, and apply steady pressure while driving. The self-drilling tip will create its own pilot hole as you go. Avoid over-tightening to prevent material damage, and use the correct driver speed and torque for your material.

Ideal for heavy-duty fastening in both indoor and outdoor settings, such as mounting metal panels to wood frames, securing sheet metal, or attaching fixtures to walls where a strong hold is needed and pre-drilling is impractical.

Yes, they are designed for indoor and outdoor use due to their hardened steel construction and corrosion resistance. For extreme exposures, ensure compatibility with other materials to minimize galvanic effects.

For a quick comparison with close alternatives on Fepy, consider these nearby options: 1) Stainless Steel Self-Drilling Screw 8mm x 1-1/4" — https://fepy.com/product/8mm-x-1-1-4-self-drilling-screw-stainless-steel-per-pkt 2) Zinc-Plated Self-Drilling Screw 8mm x 1-1/4" — https://fepy.com/product/8mm-x-1-1-4-self-drilling-screw-zinc-plated-per-pkt. Both variants offer different corrosion profiles and price points, so choose based on environment and budget.

Wear safety glasses to protect eyes from metal shavings, use gloves to prevent hand injuries, and follow proper torque to avoid stripping threads or damaging the fastened materials. Keep screws and tools out of reach of children, and store in a dry place to prevent rust when not in use.

Consider material thickness, base material (wood, metal, drywall), and the load you expect. The 8 mm diameter and 1-1/4" length offer a strong hold for thicker materials. If you need a different corrosion resistance, look at stainless or zinc-plated variants; if you need a longer or shorter length, search for other sizes in the self-drilling screw category on Fepy.

Ensure you’re using the appropriate driver for the screw head, drive at a controlled speed to prevent heat buildup, and avoid over-tightening. Pair the screw with compatible fixing materials and, if joining dissimilar metals, consider protective coatings or sealants to reduce galvanic corrosion over time.

Absolutely. The self-drilling tip and high-strength hardened steel design make them well-suited for fast, durable fixes in a variety of DIY applications, from furniture assembly to mounting panels and fixtures.
