#8 Indent Hex Washer Head Self-Drilling Sheet Metal Screws

410 Hardened Stainless Steel for Superior Strength and Corrosion Resistance

Enhance your projects with our premium #8 Indent Hex Washer Head (HWH) Unslotted Self-Drilling Sheet Metal Screws. Crafted from 410 Hardened Stainless Steel, these screws offer exceptional strength, reliable corrosion resistance, and are ideal for various applications. Please note that 410 stainless steel is always magnetic due to its martensitic structure, which also imparts the necessary hardness for self-drilling capabilities.

Material Properties of 410 Stainless Steel

410 stainless steel is a general-purpose martensitic stainless steel containing approximately 11.5–13.5% chromium. It offers a combination of:

• Good Corrosion Resistance: Effective in mildly corrosive environments such as freshwater and atmospheric conditions.
• High Strength and Hardness: Can be heat-treated to achieve various levels of hardness and mechanical properties.
• Wear Resistance: Ideal for applications where abrasion and wear are concerns.
• Magnetic Properties: Due to its martensitic structure, it is inherently magnetic.

Note: While 410 stainless steel offers good corrosion resistance, it may not be suitable for highly corrosive or marine environments where grades like 304 or 316 stainless steel are preferred.

Ideal Applications

• Sheet Metal Fabrication
• HVAC Ductwork Installation
• Electrical Enclosures and Panels
• Automotive and Trailer Repair
• Appliance Manufacturing

Why Choose These Screws?

• Self-Drilling Capability: Designed to drill through metal up to 0.150 inch thick (up to 12 gauge sheet metal) without pre-drilling, saving time and effort.
• Superior Strength and Hardness: The hardened martensitic structure provides exceptional strength and wear resistance.
• Corrosion Resistance: 410 stainless steel offers reliable corrosion resistance in mildly corrosive environments.
• Magnetic Properties: The magnetic nature facilitates easier handling and installation with magnetic tools.
• Compact Head Design: The Indent Hex Washer Head provides a large bearing surface for secure fastening while maintaining a low profile.

Installation Tips

For optimal performance when self-drilling through metal:

• Use high pressure and low speed to prevent wearing out the self-drilling tip.
• Ensure the screw is perpendicular to the work surface to prevent wandering.
• A magnetic nutsetter can aid in quick and efficient installation.

Note: These screws feature a #2 drill point suitable for thinner metals.
