Product Description

Stainless Self-Drilling Screw for Deeper Fixings

The 5.5X50MM LS SS Hex Selfdrill Bi-Metal Self-Drilling Screw A2 is engineered for reliable and efficient fixing into steel where deeper penetration is required. With a longer 50mm length and robust bi-metal construction, this screw is the go-to choice for contractors needing secure fastening in steel substrates without compromising corrosion resistance. Its A2 stainless steel body resists rust, making it ideal for outdoor or exposed applications, while the hardened carbon steel drill tip cuts cleanly into structural steel up to 12mm thick.

Designed with a hex head for optimal drive control and consistent torque, the screw allows fast installation using standard hex drivers. The bi-metal fusion of materials offers the best of both worlds—fast and powerful drilling combined with long-term durability in tough environments. This screw eliminates the need for pre-drilling, saving time and labour on-site while ensuring a high-quality, weather-resistant finish.

Ideal for industrial cladding, steel frame construction, and external metal fixings, the 5.5x50mm LS Selfdrill Bi-Metal Screw delivers peace of mind for projects requiring performance, strength, and corrosion resistance over the long term.
