Why Hardened 410 Stainless?

410 stainless steel is a martensitic alloy known for its ability to be hardened, yielding increased tensile strength and superior wear resistance compared to standard 300-series stainless. While it provides moderate corrosion resistance in many environments, its real advantage lies in durability under load—perfect for applications that demand a reliable fastener without excessive oxidation.

Ideal Applications

• HVAC Ductwork & Light Metal Fabrication
• Automotive & Machinery Component Fastening
• Sheet Metal Assembly & Maintenance
• General Construction & Repair Projects
• Bulk Orders for High-Volume Manufacturing

Bulk Benefits

• Cost-Effective: Lower cost per fastener when buying larger quantities.
• Inventory Control: Keep a steady supply on hand for streamlined operations.
• Professional Quality: Manufactured to meet consistent performance standards.

Installation Tips

• Use steady pressure to let the #2 drill point engage and cut through metal efficiently.
• Pair with a 1/4" Magnetic Nutsetter for easier alignment and faster driving.
• Maintain a perpendicular angle to the work surface for optimal thread engagement.
• Avoid over-tightening to preserve threads and extend screw life.
