براغي كناوف المسطحة قياس (3.5X11MM) تباع ضمن عبوة من (1000) برغي

The Knauf LN Waferhead Screw 3.5x11mm is a zinc-plated steel wafer-head screw designed for fastening into wood, plastic, and metal. The waferhead sits flush to the surface to reduce material damage from over-tightening and provide a clean finish. It accepts a standard screwdriver and is built for durable, long-lasting use on a variety of applications.

Specifications: size 3.5 x 11 mm, LN waferhead design, zinc-plated steel for corrosion resistance, sharp self-tapping point for easy starting, suitable for wood/plastic/metal, and sold in a box containing 1000 screws.

These screws are suitable for fastening into wood, plastic, and metal, making them versatile for furniture assembly, cabinetry, paneling, and general fastenings in mixed-material projects.

The waferhead sits closer to the surface, helping to reduce the risk of over-tightening and material crushing. This design also provides a cleaner, neater finish and helps prevent stripping in softer materials.

Each box contains 1000 screws, which is convenient for large projects or multiple applications, ensuring you have ample fasteners on hand.

Install with a standard screwdriver. For hardwoods or denser materials, pre-drilling a pilot hole is recommended to prevent splitting. Drive to a secure depth with controlled torque to avoid stripping; the self-tapping tip helps start the screw easily.

Yes, the zinc-plated steel provides corrosion resistance suitable for indoor use and general interior applications. For outdoor or highly moisture-prone environments, consider stainless steel or specialty exterior screws for better long-term durability.

Use appropriate eye protection and hand protection when handling tools. Ensure you’re using the correct driver bit to avoid cam-out. Keep screws stored in a dry place to prevent corrosion, and use suitable pilot holes to reduce material splitting.

Common applications include furniture assembly, cabinetry, paneling, fixtures, and general fastenings where a flush finish is desirable on wood, plastic, or metal surfaces.

The 3.5x13mm variant offers greater penetration depth for thicker materials, providing a longer bite than the 11mm version. Use 13mm when you need deeper engagement; for thinner materials, the 11mm version is typically sufficient.

The 4.0mm diameter provides higher shear strength and holding power in softer materials compared to the 3.5mm version, while maintaining the same 11mm length. Choose the 4.0x11mm when you need stronger grip in the same material thickness. See the alternative product here: https://fepy.com/product/knauf-ln-waferhead-screw-4-0-x-11mm-1000-box

Estimate fastener length and count by material thickness and number of joints. A box of 1000 screws is typically sufficient for medium to large projects, but always account for misdrives, reworks, and header connections to avoid running out mid-project.
