SELF DRILLING SCREW HEX HEAD STAINLESS STEEL 550

Self-drilling screws with a hex head are available in 550-grade stainless steel (a martensitic alloy, also known as A5 YUS 550) from several online merchants. They are designed for applications like fastening metal sheets and are noted for excellent corrosion resistance. 

Product Information

Corrosion Resistance: The 550 stainless steel is a specific martensitic alloy designed for high hardness suitable for self-drilling applications, offering corrosion resistance similar to 304 stainless steel, making it ideal for outdoor and harsh environments.

Applications: These screws are suitable for general metal-to-metal fixing, such as in signs, gates, and trailers. They are also used for fastening exterior decorative steel sheets to steel channels.

Design: They feature a drill-shaped point that eliminates the need for pre-drilling pilot holes in the substrate. Many come with a flanged hex head and a neoprene washer for a watertight seal, especially useful in roofing applications.
