SELF DRILLING SCREW CLASS 3 GALVANISED COUNTERSUNK PHILLIPS HEAD

Product Information
Corrosion Resistance: The Class 3 galvanised finish provides excellent corrosion resistance, making these screws suitable for outdoor use or in mild to moderate industrial or marine environments.
Application: These are primarily designed as metal self-drilling screws for fastening to steel framing or sheet metal without the need for pre-drilling, though thick or hardened steel may require a pilot hole.
Head Type: The countersunk head (often with self-embedding nibs or 'wings') is designed to sit flush or recessed within the material for a clean finish, which is ideal for mounting hinges or gate hardware.
Drive Type: They feature a Phillips head drive, commonly requiring a PH2 driver bit for installation.
Material: The screws are typically made from hardened carbon steel for durability and cutting power.
