Tlhaloso ea Sehlahisoa

Self drilling roofing screws are specially designed screws that are commonly used for roofing applications. These screws are made with a sharp point that allows them to drill through roofing materials such as metal, plastic, or wood without the need for a pre-drilled hole. The screws feature a hex head or a washer head that provides a secure connection between the roofing material and the roof deck.
