SPAX Universal Screw Flat Countersunk Head Cross Recess Z Metal Zinc Wood 5x40 mm 200 Pieces

The SPAX Universal Screw Flat Countersunk Head Cross Recess Z Metal Zinc Wood 5x40 mm 200 Pieces is a reliable fastening solution designed specifically for wood applications. Featuring a flat countersunk head and cross recess Z drive, this versatile hardware component ensures secure and flush installation in various woodworking and construction tasks. Each screw is manufactured from durable metal with a blue zinc plated A2J coating, offering essential corrosion protection for indoor projects. With a length of 40 mm, a thread diameter of 5 mm, and a thread length of 3.5 cm, these screws are engineered for efficient performance. The package contains 200 pieces, providing an adequate supply for general repairs, assembly work, and professional installations.

Advantages

These SPAX universal screws incorporate advanced engineering features to improve the installation process and final results. The integrated 4CUT design allows for screwing in without pre-drilling in many wood types, as the square end effectively displaces wood fibers to reduce material splitting, even when working close to the edge. Ground serrations extending to the point enable quick and secure fastening while reducing the driving torque required, which results in more screwed connections per battery charge when using power tools. Additionally, the MULTI head ensures a clean, flush countersinking finish by milling smoothly into wood and stopping firmly on metal surfaces.

Suitable for

• General woodworking and carpentry tasks
• Indoor furniture assembly and repair
• Attaching wooden panels and moldings
• General fastening and construction projects

When it may not be suitable

This product is not recommended for outdoor applications subject to continuous moisture or harsh weather conditions, as the zinc coating is primarily designed for indoor use. Furthermore, these screws are specifically optimized for wood materials and should not be used for direct fastening into concrete, brick, or structural metal without appropriate anchors.

How to use

To use the SPAX universal screw, align the components to be joined and position the screw perpendicularly against the wooden surface. Insert a compatible cross recess Z screwdriver or power drill bit into the fastener head. Apply steady downward pressure while operating the tool at a moderate speed. The specialized point and serrations will engage the wood fibers, pulling the screw in smoothly. Drive the fastener until the flat countersunk head rests completely flush with or slightly below the surface of the wood. Ensure not to overtighten to maintain the integrity of the surrounding material.

What to consider before purchase

• Verify that the 5x40 mm dimensions match the thickness and load requirements of your specific project
• Confirm that the intended application is indoors to ensure the zinc coating provides adequate corrosion protection
• Check that you have a compatible cross recess Z or Pozidriv driving bit for your tool
• Assess the required quantity to ensure the 200-piece pack is sufficient for your work

Usage recommendations: Always wear appropriate personal protective equipment such as safety glasses during installation. Select a power driver with adjustable torque settings to prevent stripping the cross recess Z drive or damaging the wood surface.
