Product Description

Long Stainless Fixing with Washered Seal

The 5.5X50MM LS SS Hex Selfdrill Bi-Metal Washered Self-Drilling Screw A2 is a premium fixing solution designed for secure installation into steel frameworks up to 12mm thick. This screw combines a tough carbon steel drill point with a corrosion-resistant A2 stainless steel body, delivering a reliable, high-strength fixing that stands up to demanding environments. The 50mm length provides extended reach for deeper applications, while the pre-assembled washer ensures a tight, weather-resistant seal—ideal for external use.

The hex head design allows for firm drive engagement and torque transfer using standard hex drivers, making installation quick and consistent. The washered finish not only provides improved sealing but also protects against over-driving, enhancing both performance and appearance. Engineered for fast, precise penetration without pre-drilling, this bi-metal screw reduces labour time on-site and increases fixing efficiency.

Perfect for cladding, roofing, and structural steelwork, the 5.5x50mm LS washered bi-metal screw offers peace of mind where rust-resistance, mechanical strength, and ease of installation are critical. Whether working on commercial or industrial sites, this fixing delivers lasting results with minimal maintenance.
