The main function of slotted semi countersunk wood screws is to securely connect a metal (or non-metal) part with a through-hole to a wooden component. This connection method belongs to detachable connection, and its design features include:
Connection method: Slotted semi countersunk head wood screws are similar to machine screws, but the thread on the screw is a specialized wood screw thread that can be directly screwed into wooden components (or parts).
Head design: A 90 degree conical groove is machined on the surface of the mounting hole on the connector, and the head of the flat screw is flush with the surface of the connector in this groove. This design makes the screws more aesthetically pleasing and allows for slight protrusions on the surface.
In summary, slotted wood screws are not only beautiful and practical connectors, but also ensure their reliability and safety in various applications due to their specific design and application of national standards.
