## Long description

Koelner screw for wood 3.5x45 mm with phosphate coating, supplied in a container, is a metric wood screw designed for general carpentry and construction fastening tasks. The 3.5 mm diameter and 45 mm length make it suitable for joining timber elements, fixing wooden panels, and attaching wood to light frames where a phosphate surface treatment provides basic corrosion resistance. The screw head and drive are matched for common screwdrivers and impact drivers used in woodworking.
Advantages
The phosphate coating offers a uniform, corrosion-resistant surface suitable for indoor and semi-exposed applications where high-grade galvanization is not required. Its standard metric dimensions and consistent manufacturing tolerances ensure predictable penetration and holding performance in soft and medium-density woods. Supplied in a container, the screws are easy to store and handle on site, reducing time spent counting or transferring loose fasteners.
Suitable for
 Joining wood-to-wood connections in furniture and frame assembly
 Fixing wooden cladding, battens, and panels
 Attaching wooden elements to light timber or metal subframes when phosphate coating is acceptable
 General carpentry, interior trim, and repair works
Key specifications
 Diameter: 3.5 mm
 Length: 45 mm
 Surface treatment: phosphate coating for basic corrosion resistance
 Head and drive type: compatible with standard woodworking screwdrivers and impact drivers
 Packaging: supplied in a storage container for convenient handling
How to use
Select a screw length appropriate to the combined thickness of materials, ensuring sufficient penetration into the receiving timber without protrusion. Pre-drilling a pilot hole is recommended for hardwoods or when close tolerances are required; use a drill bit slightly smaller than 3.5 mm for a tight fit or up to the core diameter for easier driving. Use a compatible screwdriver or a low-torque impact driver to drive the screw until the head is flush with or slightly below the surface, avoiding overtightening which can strip the wood or damage the coating.
Usage recommendations
For outdoor or highly humid environments, consider using screws with enhanced corrosion protection, such as galvanised or stainless steel fasteners. Store the container in a dry place to maintain the integrity of the phosphate coating and handle with appropriate PPE when cutting or drilling wood.
