Description

Hex head-self drilling screw are a type of fastener designed to drill into metal without the need for pre-drilling. They have a pointed tip that cuts into the material, creating a pilot hole as it drives in. This makes them a convenient and time-saving option for various applications.

Features

★ Hex Head: This provides a secure and easy grip for a socket wrench or hex key, making installation efficient.
★ Self-Drilling Tip: The pointed tip allows the screw to drill into metal without requiring a pre-drilled hole.
★ Thread Formation: As the screw is driven in, it forms its own threads in the material, creating a secure fastening.
