Material: Steel
Application: Timber and wood-based materials
To use these screws, ensure you have a compatible screwdriver or power drill with the appropriate bit size. Position the material to be fastened against the wooden base and drive the screw perpendicularly into the surface. It is recommended to apply steady pressure to ensure the screw head sits flush with the material surface without over-tightening, which could damage the wood fibers.
What to consider before purchase
Verify the thickness of the material being fastened to ensure the 33 mm length is sufficient.
Ensure the screw type is compatible with the specific density of the wood being used.
Check the total quantity required for your project to ensure the 1000-piece pack meets your needs.
Usage recommendations
For best results, pre-drilling a pilot hole is recommended when working with hardwoods to prevent splitting and to ensure a clean, professional finish.
