Security Button Head AB Self Tapping Screws

Security Self Tapping Screws are designed to provide both fastening strength and tamper-resistance, making them ideal for applications where security is a priority. These screws feature a button head design, offering a smooth, rounded profile that not only provides a neat, low-profile finish but also reduces the risk of snagging or interference.

Available security drive types include:

• Pin Torx – a star-shaped drive with a central pin, providing excellent torque transfer and strong resistance against tampering with standard tools.
• Pin Hex – a hexagonal drive with a central pin, combining simplicity with effective security against unauthorised removal.
• 5-Lobe – a unique five-lobed design that offers advanced security, making it highly resistant to tampering compared with more common drive styles.

Manufactured in A2 (304) Stainless Steel and A4 (316) Stainless Steel, these screws deliver excellent corrosion resistance, making them suitable for both indoor and outdoor use—even in harsh or marine environments.

What is an AB Self Tapping Screw?
AB Self Tapping Screws are a common type of thread-forming fastener. The "AB" designation refers to their sharp point and coarse threads, which allow them to cut their own mating threads into softer materials such as sheet metal, plastics, or wood. Unlike traditional machine screws, they don't require a pre-tapped hole—only a correctly sized pilot hole. This makes them highly versatile and time-saving in installation.

Why Choose a Security Screw Over a Regular Drive?
Security screws are specifically engineered to deter tampering, theft, and vandalism. Unlike standard Phillips or Pozi drives, which can be easily undone with common tools, Pin Torx, Pin Hex, and 5-Lobe drives require specialised drivers or bits. This reduces the likelihood of unauthorised removal and provides peace of mind in applications such as:

• Public fixtures and signage
• Safety equipment
• Access control panels
• Outdoor installations exposed to theft or interference

By choosing these security screws, you're adding an extra layer of protection and ensuring your fixings remain intact where reliability and safety matter most.
