Why Hardened 410 Stainless?

410 stainless steel can be heat-treated to enhance tensile strength and wear resistance, surpassing standard 300-series stainless in demanding metal-to-metal tasks. It provides moderate rust protection, making it suitable for indoor and many outdoor applications.

Ideal Applications

• Construction & Steel Framing Projects
• Automotive & Equipment Repairs
• HVAC, Industrial Ductwork & Fabrication
• Appliance & Electronics Assemblies
• Any Bulk Job Requiring High-Strength, Flush-Finish Screws

Installation Tips

• Use a square/Robertson drive bit to minimize cam-out and driver wobble.
• Apply steady pressure so the #3 self-drilling tip can bore effectively through metal.
• Maintain a perpendicular approach to ensure a flush seat of the flat head.
• Avoid over-tightening to preserve threads and ensure optimal clamping force.
