Product Information
Full details
The Countersunk Wood Screw (6 x 100mm) is designed for professional contractors and DIY enthusiasts who require a reliable, heavy-duty fastener for substantial timber projects. Its primary benefit is a durable yellow-passivated finish that provides superior corrosion resistance for both indoor and outdoor applications, though users should note that the 100mm length is best suited for thick material substrates and may require pre-drilling to prevent wood splitting.

FAQs
Can these screws be used outdoors?
Yes, the yellow-passivated finish provides protection against corrosion, making them suitable for outdoor wood projects.
Do I need to drill a pilot hole?
While the screws are designed to bite well, pre-drilling is highly recommended when working with hardwoods or near the edge of a board to prevent splitting.
Are these screws suitable for metal frames?
No, these are specifically designed for wood applications and may not hold securely in metal substrates.
What is the diameter of the screw?
The screw has a diameter of 6mm.
How many screws are included in the pack?
This set includes 100 pieces per pack.
Why is the coating yellow?
The yellow-passivated finish is a chemical process that adds a layer of protection to the steel, helping to prevent rust and oxidation.
Troubleshooting
Screw head strips during installation
Ensure you are using the correct size screwdriver bit and that the bit is fully seated before applying pressure.
Timber splits when driving the screw
Create a pilot hole using a drill bit smaller than the screw diameter to relieve stress in the wood fibers.
Screw binds before fully seated
Check if the pilot hole depth is adequate and ensure the screw is entering the wood at a perpendicular angle.
Pros and Cons
Pros
- High corrosion resistance due to yellow-passivation
- Countersunk head sits perfectly flush with the wood surface
- Substantial length suitable for structural applications
- Bulk quantity ensures project readiness
Cons
- Requires pre-drilling in hardwoods to avoid splintering
- Not suitable for use in masonry or metal without specific anchors
- Yellow finish may not be aesthetically desirable for fine furniture
Setup, Compatibility & Care
For optimal performance, always ensure you are using a drill bit or screwdriver tip that matches the screw head size to prevent cam-out. When working with dense lumber, it is recommended to drill a pilot hole slightly smaller than the 6mm screw diameter to facilitate an easier drive and protect the timber from splitting. For long-term maintenance, ensure the screws are driven completely flush to the surface to prevent water from pooling in the countersink area. Store in a dry location to maintain the effectiveness of the passivation coating.
