In this category, you will find the different types of wood screws.
Wood screws are essential fasteners for assembling wooden parts, characterized by a wide thread and, often, a countersunk head to fit perfectly into the surface.
Characteristics and types
The choice of a wood screw depends on several factors, including the type of wood (hard or soft), the intended application, and the desired level of strength.
- Material :
- Steel: Highly resistant, steel is ideal for structural assemblies and hardwoods, as it withstands excessive tightening well. It is often zinc-plated or bichromated for better corrosion protection.
- Stainless steel (Inox): Recommended for outdoor use (terraces, cladding) or in humid environments, thanks to its excellent resistance to rust.
- Brass and Bronze: Softer than steel, these materials are often chosen for their aesthetic appeal in fine joinery or the restoration of antique furniture, offering good adhesion but less mechanical resistance.
- Head: The countersunk head is the most common, designed to sit flush with the wood. Other shapes exist, such as round, oval, or domed heads, used for aesthetic reasons or specific applications.
- Drive size: The drive size determines the tool needed for screwing. The most common types are:
- Slotted (flat): Traditional but less practical.
- Cruciform (Philips/Pozidriv): Very common for its ease of use.
- Torx (star): Offers better control and reduces the risk of the tool slipping, particularly useful for powerful screwdriving.
- Threading:
- Full thread: The thread runs the entire length of the screw, ensuring maximum grip between the two pieces of wood being joined.
- Partial threading: A smooth section under the head allows the upper part to be pressed against the lower part, providing better tightening.
Usage tips
For optimal results, especially with hardwood , pre-drilling is recommended . The drill bit diameter should be slightly smaller (0.5 to 1 mm less) than the screw diameter to ensure a secure grip without splitting the wood.
The length of the screw should generally be sufficient so that two-thirds of the thread penetrates the fixed (thickest) part, thus ensuring a solid fixing.
All you have to do now is choose your required lengths, sections and quantities!
