Timco Solo Chipboard & Wood Screws - 4mm x 50mm - Yellow

Wax lubrication reduces friction, making screw insertion easier, increasing driving torque, and providing some corrosion resistance.

They are designed for use in various types of timber, man-made boards, and masonry when used with plastic plugs.

A countersunk head is designed to sit flush with the surface of the material, providing a neat and clean finish.

Pre-drilling is recommended, especially in hardwoods, to prevent splitting and ensure easier insertion.

Use a driver bit that matches the screw head type. Most of these screws require a Phillips or Pozi drive bit.

Fully threaded means that the entire shaft of the screw is threaded, providing maximum grip.

Consider the thickness of the materials you are joining, and the desired holding strength. Ensure the screw length is appropriate to penetrate sufficiently into the base material.

Use the correct driver bit and apply consistent pressure. If the issue persists, try a different screw or pre-drill a larger pilot hole.

Ensure the pilot hole is correctly sized and that the screw is being driven straight. A countersinking bit can also help.

Pre-drill a pilot hole. Reduce driving speed, especially in hardwoods.
