Key Features & Benefits

• Superior Thread Design: Features serrated V-threads that achieve optimum insertion and holding power in all masonry types, including concrete, brick, stone, and concrete block. The first 30mm incorporates a high-low thread design to aid insertion and significantly reduce driving torque, making installation quicker and easier.
• Enhanced Durability & Safety: Constructed from all-steel, these screws are zinc-plated and yellow passivated for increased corrosion resistance, ensuring longevity in various environments. Crucially, as a non-flammable, all-steel fixing, it conforms to the BS 7671 standard's 18th edition, which requires wiring systems to be supported by materials unlikely to prematurely collapse in the event of a fire.
• Secure & Efficient Installation: The flat countersunk head is designed with five locking ribs to prevent rotation during tightening, providing a flush, secure finish. The TX30 drive recess minimises driver wear and prevents 'camming-out', ensuring a positive connection and efficient installation every time.
• Versatile Application: This screw is ideal for a multitude of applications, most notably for fitting windows and door frames securely into masonry. It serves as a direct, robust replacement for older, less reliable anchoring methods, offering a faster and more dependable result.
