Bugle Head Self-Drilling Screws

Application:

Bugle head self-drilling screws are commonly used in construction, carpentry, drywall installation, and various woodworking projects. They are suitable for attaching materials such as wood, metal, and plastic. These screws are ideal for applications where a flush or slightly recessed finish is desired, providing a clean and professional appearance.

Features:

Bugle head self-drilling screws are typically made of hardened steel or stainless steel, which provides strength and corrosion resistance. They have a sharp, drill-like point at the tip, allowing them to penetrate and drill into materials without the need for pre-drilling. The bugle head design allows for a flush or slightly recessed finish when driven into the surface.
