Flat Tail Tapping Head Screw Materials

Flat-tail tapping head screws are available in a variety of materials, each with its own unique properties and applications. Here is an overview of the commonly used materials for flat-tail tapping head screws:

Carbon Steel

Carbon steel is a popular choice for flat-tail tapping head screws due to its strength and durability. It has high hardness, making it suitable for applications that require strong and long-lasting fasteners. Carbon steel screws are often used in construction, manufacturing, engineering, and assembly. They are known for their efficient performance and can be found in various industries. Additionally, carbon steel screws can be treated with zinc or nickel plating to enhance their corrosion resistance and improve their overall appearance.

Stainless Steel

Stainless steel is another common material for flat-tail tapping head screws. It offers excellent strength and durability, similar to carbon steel. Stainless steel screws are known for their high hardness and long service life. They are smooth, burr-free, and resistant to corrosion and rust. Stainless steel screws are ideal for applications where strength and corrosion resistance are important, such as in the machinery industry, furniture, and automobile or motorcycle maintenance.

Black Zinc Plating

Some flat-tail tapping head screws feature black zinc plating, which provides a uniform coating and enhances the screw's smoothness. This treatment improves the screw's hardness, making it highly resistant to corrosion and rust. Black zinc-plated screws typically have a deep thread design, providing strong penetration and maximum clamping force. They are often used for DIY projects and special applications.

Blue Zinc Plating

Blue zinc plating is another surface treatment option for flat-tail tapping head screws. It imparts a smooth and uniform finish to the screw, enhancing its overall appearance. Blue zinc plating also increases the screw's hardness, making it highly resistant to corrosion and rust. Screws with blue zinc plating usually have a precise thread design, providing strong penetration and secure fastening.

High-Quality Materials

Flat-tail tapping head screws are also available in unspecified "high-quality materials." These screws are designed to be rugged and durable, ensuring ease of use and long-lasting performance. They often feature a smooth surface and are free from burrs, making them ideal for applications where a smooth and practical finish is desired.

Flat Tail Tapping Head Screw Sizes

Flat-tail tapping head screws are available in a variety of sizes to suit different applications. The size of a screw is typically defined by two measurements: the thread diameter and the screw length. Here are some standard sizes for flat-tail tapping head screws:

M3.5 x 10mm

This screw size has a thread diameter of 3.5mm and a length of 10mm. It is often used for sheet metal applications and is made of black-zinc carbon steel.

M1.8 x 4mm

With a smaller thread diameter of 1.8mm and a length of 4mm, this size is suitable for precision applications. It features a Phillips flat head and is made of carbon steel.

M2, M2.3, M2.6

These screws are available in three different sizes, all with a small diameter. The uniform pitch and smooth surface make them suitable for electronic applications. They are made of carbon steel and feature a round head with a flat tail.

5mm x 40mm

For applications requiring a larger head, this screw size features a thread diameter of 5mm and a length of 40mm. The blue zinc plating provides corrosion and rust resistance, while the deep thread ensures a strong clamping force.

When selecting a screw size, it is important to consider the specific application and choose a screw that meets the required dimensions and material specifications. Flat-tail tapping head screws are versatile and can be used in various materials, including wood, plastic, and metal.

Flat Tail Tapping Head Screw Uses

Flat-tail tapping head screws are a type of self-tapping screw, which means they create their own threads in the material they are fastening. They are often made of carbon steel and can be zinc-plated or blue zinc-plated to resist corrosion and rust. They come in a range of sizes, with thread diameters and screw lengths varying according to specific requirements.

Flat-tail tapping head screws are ideal for projects where the screw head should be flush with the surface of the material, or not protrude at all. This makes them well-suited for use in plumbing and electrical applications, as well as any other scenarios that require practical access to the screws.

These screws are commonly used in the construction and building industry, especially for assembling modular structures and installing drywall. They are also popular in woodworking and cabinetry, as they simplify the assembly process by creating their own threads. The automotive industry uses them for installing parts and attaching panelling, while the electronics and electrical sectors find them useful for achieving firm attachments. Additionally, flat-tail tapping head screws are perfect for attaching roofing sheets and metal siding.

When installing a flat-tail tapping head screw, it is important to choose the right size and thickness for the specific application. Mark the precise location for the screw and consider drilling a pilot hole, especially when working with harder materials like metal or hardwood. Place the screw tip into the hole or marked position, ensuring that the drill driver or manual screwdriver is at a 90-degree angle for a straight insertion. Start turning the screw slowly and consistently, allowing it to create threads within the material until the head is flush with the surface. Check the alignment and tighten the screw if needed.

Flat Tail Tapping Head Screw Finishes

Flat tail tapping head screws are available in a variety of materials and finishes. The choice of finish depends on the intended application and the desired appearance of the screw. Here are some common finishes for flat tail tapping head screws:

Zinc-Plated

Zinc-plating is a common finish for flat tail tapping head screws. It involves coating the screw with a layer of zinc to provide corrosion resistance and improve the screw's durability. This type of finish is often used for screws made of carbon steel, such as the M3.5x10mm pan head flat tail self-tapping screws made of black-zinc carbon steel.

Blackening

Blackened flat tail tapping head screws are also available. This finish is created by applying a black coating to the screw, resulting in a sleek and practical appearance. The black round head tailing self-tapping screws with a flat tail self-attack feature this finish and are made of carbon steel.

Blue Zinc Plating

Blue zinc plating is another option for flat tail tapping head screws. This process involves applying a blue zinc coating to the screw, which provides corrosion and rust resistance. The coating is uniform and smooth, enhancing the overall smoothness of the screw. An example is the large head self-tapping screw with a TA mushroom umbrella head and a pointed tail.

Stainless Steel

Flat tail tapping head screws are also available in stainless steel, which is known for its corrosion resistance and durability. An example is the M2 x 4 mm pan head flat tail Phillips self-tapping screws made of 304 stainless steel. This type of finish is suitable for applications where corrosion resistance and strength are important.

Nickel Plating

Nickel plating is another finish option for flat tail tapping head screws. It provides a smooth and uniform coating that enhances the appearance and protects the screw from corrosion. The specific type of nickel plating used in conjunction with zinc plating for certain flat head tail tapping screws is not specified, but it likely improves corrosion resistance and overall durability.
