Product Description

5.5/6.3 x 25mm Bi-Metal Washered Self-Drilling Screw – A2 Stainless Steel

The 5.5/6.3 x 25mm Bi-Metal Washered Self-Drilling Screw is a high-performance fastener engineered for secure installation in steel structures and sandwich panels. The integrated washer enhances load distribution and provides a watertight seal, making it ideal for demanding environments.

Manufactured from A2 stainless steel with a hardened carbon steel cutting tip, this self-drilling screw ensures quick and trouble-free penetration into metal surfaces. The dual-thread design optimises grip, preventing panel deformation and ensuring a reliable hold.

For best results, install at a 90-degree angle using a cordless impact screwdriver with a torque setting of 1600 - 2000 rpm. Reduce speed when the washer begins to deform to achieve a secure, long-lasting connection.
