These fasteners feature a 300 series stainless steel head and threads fused to hardened steel lead threads, ensuring durability and strength. The self-drilling point allows for quick and efficient installation, making them ideal for a wide range of projects.

The fasteners are made from hardened steel tapping threads and point fused onto an 18-8 stainless steel shank and head, providing superior strength and corrosion resistance. Each fastener is coated with Stalgard GB, a galvanic barrier that protects against corrosion and extends the life of the fastener.
