Different types of wood screws for softwood, hardwood, plywood, MDF and timber

When choosing the right type of wood screw for your project, there are many factors to consider, from the length and material of the screw to the shape of its head and the type of drive required to insert it.

Softwood

Softwood screws have a lower thread count per inch to prevent the fibres of the wood from being torn apart. Softwood screws are also designed to prevent the wood from splitting without pre-drilling.

Hardwood

Hardwood screws have a higher thread count, with tighter threads, to ensure the screw has sufficient holding strength in denser woods.

Plywood

Plywood screws are designed to be used with other sheet goods, such as particleboard and MDF. They have a coarser thread and a sharper point to penetrate the wood without the need for a pilot hole.

MDF

MDF screws should have a coarse thread due to the layered nature of the material. Euro cabinet screws are often used for MDF, as they have a wider shank, which provides a superior surface area.

Timber

For timber, you can use either a wood screw or a production screw. Production screws are made from carbon steel heat-treated to provide a good balance of hardness and toughness. They are designed to penetrate the hardest woods and even some metals.

Types of Screw Head

Pan Head

Pan head screws have a rounded top and a flat underside. They are best for attaching sheet metal, Plexiglass, or other thin materials to wood.

Flat Head

Flat head screws have a flat top and a cone-shaped underside, allowing the head to sink into the wood and sit flush with the surface. They are typically used for countersinking and for fastening wood to wood.

Washer Head

Washer head screws have a rounded head with a built-in washer and a flat bottom. They are commonly used in pocket hole joinery.

Square drive for high torque and minimal slippage

Square drive screws, also known as Robertson screws, are a type of screw with a square-shaped socket in the screw head and a matching square protrusion on the tool. This design allows for a more secure fit between the screw and the driver, resulting in increased torque and reduced slippage.

The square drive provides several advantages over other types of screws. Firstly, it offers greater resistance to "cam out", which is when the driver bit slips out of the screw recess. The square shape of the socket and tool provides a tighter fit compared to other drive types, reducing the likelihood of slippage during use.

Another benefit of square drive screws is their ability to be driven one-handed. The tapered design of the screw and the matching bit create a matched fit system, allowing the screw to stick to the bit. This makes it easier for users to drive the screw with one hand, as they don't need to worry about the screw wandering or falling off the driver.

Additionally, square drive screws are known for their strength and durability. They are made of heat-treated steel, providing dependable strength for demanding applications. The sharp thread angle of the screw cuts into the wood, minimizing cracking or splitting, and the optimized thread depth and spacing help prevent crumbling between threads for better holding power.

Square drive screws also have a sharp point, which allows for quick and easy starting, even without a pilot hole in many materials. The minimum body diameter of the screw reduces driving resistance, making it easier to drive the screw into the material.

Overall, square drive screws offer improved torque, reduced slippage, and enhanced efficiency for woodworking and construction projects. They are a popular choice for builders and woodworkers due to their strength, ease of use, and ability to be driven one-handed.

Black oxide finish for corrosion resistance and sleek appearance

#6 button head wood screws with a black oxide finish offer both functionality and a sleek appearance. Black oxide, also known as blackening, is a chemical treatment that converts the top layer of a ferrous material, adding corrosion and abrasion resistance, as well as a deep black colour. This finish is commonly used on fasteners like wood screws to enhance their performance and aesthetics.

One of the key benefits of the black oxide finish is its corrosion resistance. While it provides mild to excellent corrosion resistance, it can be enhanced further by impregnating the black oxide with oil or wax, which seeps into the porous surface, creating an extra layer of protection. This additional step is crucial for maximising the corrosion-resistant properties of the black oxide treatment.

The black oxide finish is also prized for its sleek and clean appearance. It offers a nice, deep black look that is often favoured in the automotive industry. Additionally, the black oxide treatment does not significantly alter the dimensions of the screws, making it ideal when tight tolerances are essential. This finish is also economical, providing corrosion resistance at a lower cost compared to methods like electroplating.

The process of applying the black oxide finish involves dipping the screws into different tanks of chemical treatments, including an alkaline detergent, water, and sodium hydroxide at elevated temperatures. This treatment converts the surface of the metal into magnetite (Fe3O4), which provides better corrosion protection than red oxide (rust). The final step involves applying a sealant, typically oil, to seal the porous surface and enhance corrosion resistance.

Overall, the black oxide finish on #6 button head wood screws provides a combination of functionality and aesthetics. It offers mild corrosion and abrasion resistance, a sleek black appearance, and minimal dimensional changes, making it a versatile and cost-effective choice for various applications.

Hex socket drive for secure tightening

Hex socket drives are a type of screw head that can be used to securely tighten 6 button head wood screws. They are known for their ability to facilitate high torque installation, resulting in a secure and stable fit. The deep socket head design of hex socket drives allows for higher torque and a more secure installation, providing a flush and professional finish.

One example of a hex socket drive screw is the Hillman #10 x 1/2-in Socket Hex-Drive Sheet Metal Screw, which can be used with wood, among other materials. These screws feature sharp threads that cut into materials and are highly versatile. Hex socket drives are also available in a range of sizes and lengths to suit different project requirements.

Another benefit of hex socket drive screws is their ease of installation.
