Product Q&A

Q:What materials can this screw be used for?

It is suitable for solid wood, plywood, particleboard, MDF and other wood-based materials. The appropriate size should be selected according to the application.

The square drive provides stable bit engagement and efficient torque transfer. The countersunk head can sit flush with the wood surface for a neat finish.
