Countersunk Self Tapping DIN 7982 Screws

The Sealey 4.2mm x 25mm Countersunk Self Tapping Screw combines a sturdy 4.2mm diameter with an extended 25mm length, making it particularly well-suited for securing thicker materials or applications requiring deeper thread engagement. This size variant excels when fixing through composite materials, attaching brackets to metal frames, or any situation where both strength and penetration depth are important considerations. These screws are manufactured to the demanding DIN 7982 standard, ensuring consistent threading, reliable performance, and professional quality. The countersunk head design allows the screw to sit flush with the material surface, creating a smooth finish that won't catch or protrude—essential for safety and aesthetics in visible locations. The Pozi head drive delivers superior torque transfer and significantly reduces the risk of cam-out, allowing efficient installation whether using manual drivers or power tools. Each pack contains 100 screws housed in a practical resealable bag that keeps your fixings organised and protected from workshop conditions. This packaging makes the screws easy to store, transport, and access during projects.
