ABOUT THIS CATEGORY
Bugle head screws are self-drilling screws commonly used to fasten relatively softer materials such as drywall. They have a head sectional profile resembling the bell of a trumpet or bugle. Additionally, their heads are designed to compress drywall paper and gypsum to form their countersink hole while being installed. Bugle head screws come in both imperial and metric standard sizes and are available in various lengths.
