Question 1

What is the Knauf LN Waferhead Screw 3.5x11mm and what is it used for?

Accepted Answer

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.

Question 2

What are the key specifications of this screw?

Accepted Answer

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.

Question 3

What materials can I fasten with these screws?

Accepted Answer

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.

Question 4

How does the waferhead design help during installation?

Accepted Answer

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.

Question 5

How many screws come in a box, and is this suitable for large projects?

Accepted Answer

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

Question 6

What is the recommended installation guidance for these screws?

Accepted Answer

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.

Question 7

Are these screws corrosion resistant and suitable for indoor use?</

Accepted Answer

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.

Question 8

What safety notes should I consider when using these screws?

Accepted Answer

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.

Question 9

What are common use cases for this screw?

Accepted Answer

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

Question 10

How does this screw compare to the Knauf LN Waferhead Screw 3.5x13mm?

Accepted Answer

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.

Question 11

How does this screw compare to the Knauf LN Waferhead Screw 4.0x11mm?

Accepted Answer

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

Question 12

How should I plan quantities for a project?

Accepted Answer

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.
