DIN 571 hex head wood screw uses

DIN 571 hex head wood screws, also known as lag bolts, are used to support heavier loads than standard wood screws. They are commonly made from stainless steel and are available in a range of sizes, such as 5 x 30mm and 5 x 50mm. These screws require a pilot hole and are suitable when a large amount of torque is needed.

DIN 571 hex head wood screws are often zinc-plated to provide additional corrosion resistance. This type of screw is typically used for outdoor applications or in environments where the screw may be exposed to moisture or other corrosive substances. The zinc plating acts as a sacrificial layer, protecting the underlying steel from corrosion.

One common use of DIN 571 hex head wood screws is in construction and woodworking projects. They are often used to fasten large pieces of wood together, such as in timber framing, deck building, or furniture construction. The hexagonal head provides a secure grip for tools, allowing for the application of high torque during installation.

Additionally, DIN 571 hex head wood screws are used in various industrial and engineering applications. They can be found in machinery, equipment mounting, and structural connections. The ability to apply high torque makes these screws suitable for applications where a strong and secure connection is required.

Furthermore, these screws can be utilised in applications requiring a decorative or aesthetically pleasing appearance. The hexagonal head can provide a unique visual appeal, making them suitable for use in furniture, cabinetry, or other visible applications.

DIN 571 hex head wood screw sizes

DIN 571 hex head wood screws are available in a wide range of sizes to meet various fastening needs. The size of a screw is determined by two main factors: the length and the diameter. Here is an overview of the different dimensions available for DIN 571 hex head wood screws:

Length:

• The length of the screw is a critical factor and is measured from the tip of the screw to the bottom of the head. DIN 571 hex head wood screws are available in various lengths, including 90mm, 160mm, and 300mm. For example, the patent wood screw DIN 571 is sized at 16x300, indicating a length of 160mm.
• It's important to select the appropriate length for your specific application. Too short a screw may not provide sufficient holding power, while a screw that is too long can protrude and cause damage or injury.

Diameter:

• The diameter of the screw refers to the thickness and is measured at the widest point of the thread. DIN 571 hex head wood screws are available in various diameters, such as M10 and 12mm. For instance, the HEX WOOD SCREW DIN 571 A2 M10X40 has a diameter of 10mm and a length of 40mm.
• Choosing the correct diameter is crucial for a secure fit. A screw that is too thin may not provide enough strength, while a screw that is too thick can damage the material or be difficult to insert.

Thread Length:

• The length of the threaded portion of the screw is another important consideration. DIN 571 hex head wood screws have a minimum thread length specified, ensuring sufficient engagement with the material.
• Insufficient thread length can result in reduced holding power, while excessive thread length may weaken the screw or cause difficulty during installation.

Head Height:

• The head height of a screw refers to the distance from the base of the head to the top of the hex head. This dimension is crucial for ensuring the screw head sits flush with or below the surface of the material.
• DIN 571 hex head wood screws have a specified minimum head height to prevent the head from being too low and potentially weakening the screw.

Circumscribed Circle Diameter:

This dimension refers to the minimum diameter of a circle that can be drawn to circumscribe the hex head of the screw. It ensures the hex head is not too small, providing adequate torque and grip during installation and removal.

When selecting a DIN 571 hex head wood screw, it is essential to consider the specific application and choose the appropriate size to ensure a secure and safe fastening.

DIN 571 hex head wood screw materials

DIN 571 hex head wood 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 DIN 571 hex head wood screws:

Steel

Steel is a strong and durable material that is often used for DIN 571 hex head wood screws. It offers excellent load-bearing capacity and is suitable for applications where high torque and support for heavier loads are required. Steel screws are typically galvanised to provide corrosion resistance and improve their appearance.

Stainless Steel

Stainless steel is a popular choice for DIN 571 hex head wood screws due to its corrosion resistance and aesthetic appeal. It is available in different grades, such as A2 and A4, offering varying levels of corrosion protection. Stainless steel screws are ideal for applications where strength and durability are needed, along with resistance to the elements.

Zinc-Plated

Zinc-plated DIN 571 hex head wood screws offer enhanced corrosion resistance. The zinc plating acts as a sacrificial layer, protecting the underlying screw material from oxidation. This type of screw is commonly used in outdoor applications or where moisture may be present.

Plastic

While less common, plastic DIN 571 hex head wood screws do exist. Plastic screws are lightweight and may be used in applications where corrosion resistance is important but lower weights are required.

Non-Ferrous

Non-ferrous metals, such as brass or copper, can also be used for DIN 571 hex head wood screws. These materials offer unique properties, such as corrosion resistance and electrical conductivity, making them suitable for specific applications.

DIN 571 hex head wood screw finishes

DIN 571 hex head wood screws are available in a variety of materials and finishes. The choice of finish depends on the intended application and the desired appearance. Here are some of the common finishes for DIN 571 hex head wood screws:

Zinc-Plated

Zinc plating is a common finish for DIN 571 hex head wood screws. It involves coating the screw with a thin layer of zinc to provide corrosion resistance and improve the screw's durability. Zinc-plated screws are often used in outdoor applications or in environments where moisture is present. They offer a balance between cost and corrosion protection.

Stainless Steel

Stainless steel is another popular finish for DIN 571 hex head wood screws. Stainless steel screws are known for their corrosion resistance and strength. They are typically made from an alloy of iron, chromium, and other elements. A2 and A4 are common grades of stainless steel used for these screws, with A2 being the most common. Stainless steel screws are suitable for applications where corrosion resistance and strength are important, such as in outdoor furniture or marine environments.

White Galvanized

White galvanized DIN 571 hex head wood screws are also available. Galvanization is a process where a zinc coating is applied to the screw, providing corrosion protection. The white color is achieved by adding a layer of paint or coating over the zinc plating. White galvanized screws are often used in applications where a decorative or aesthetically pleasing appearance is desired, such as in furniture or woodworking projects.

Plain Finish

DIN 571 hex head wood screws can also be found with a plain finish, which means they have no additional coating or plating. These screws are typically made of steel and are suitable for applications where corrosion resistance is not a primary concern. Plain finish screws are often used in indoor applications or where the screw will be covered or painted over.

Other Finishes

In addition to the finishes mentioned above, DIN 571 hex head wood screws can also be found with specialized coatings or treatments to suit specific applications. For example, some screws may be coated with a colored finish to match a particular décor or environment. Additionally, some screws may have a wax or oil coating to facilitate easier driving and reduce friction during installation.

When selecting a finish for DIN 571 hex head wood screws, it is important to consider the intended application, the level of corrosion resistance required, and the desired appearance of the finished product.
