Stainless Tek Screw w/ Washer

SS304 BI-Metal Tek Screw w/ Washer & Stainless Grade 410 Tek Screw w/ Washer

SS304 BI-Metal Tek Screw w/ Washer

Description: The SS304 BI-Metal Tek Screw with Washer is engineered for tough, corrosion-prone environments. Combining a premium stainless steel SS304 body with a hardened carbon steel tip, this screw offers exceptional corrosion resistance alongside self-drilling capability. The built-in washer ensures a tight, secure, and leak-proof connection, making it ideal for metal-to-metal fastening, especially in outdoor and marine environments.

Properties:

• Material:
  • Body: SS304 Stainless Steel, excellent for corrosion resistance.
  • Tip: Hardened carbon steel for enhanced drilling efficiency.
• Corrosion Resistance: Outstanding, particularly in marine or outdoor applications.
• Head Type: Typically hex or Phillips head for easy installation.
• Washer: Integrated washer to create a watertight, secure seal.
• Thread Type: Self-tapping for fastening into metal without pre-drilling.
• Drilling Capacity: Can drill through metal sheets and materials up to 12-14 gauge, depending on size.
• Temperature Resistance: Excellent performance in extreme temperatures.

Usage:

• Roofing & Cladding: The washer offers a watertight seal, making it perfect for metal roofing and cladding installations.
• Marine & Outdoor Applications: The SS304 body’s high corrosion resistance makes it ideal for coastal or marine environments.
• HVAC Systems: Suitable for fastening in HVAC units where exposure to moisture requires a rust-resistant solution.
• Metal-to-Metal Fastening: Perfect for attaching metal components without the need for pre-drilling.
• General Construction: Used in environments where high corrosion resistance is needed alongside strong fastening power.

Stainless Grade 410 Tek Screw w/ Washer

Description: The Stainless Grade 410 Tek Screw with Washer is designed for heavy-duty fastening applications where strength and durability are paramount. Made from Grade 410 stainless steel, this screw offers higher hardness and strength compared to SS304, but with slightly lower corrosion resistance. The hardened Grade 410 material ensures reliable self-drilling performance through harder metals, while the integrated washer provides a secure, watertight seal.

Properties:

• Material: Grade 410 Stainless Steel, offering high tensile strength and moderate corrosion resistance.
• Corrosion Resistance: Good, but slightly less than SS304; suitable for moderately corrosive environments.
• Head Type: Typically hex or Phillips for secure, easy fastening.
• Washer: Integrated washer for tight, leak-proof connections.
• Thread Type: Self-drilling tip that allows for fast, efficient drilling through hard metals.
• Drilling Capacity: Capable of drilling through thicker metal sheets, including steel and aluminum, up to 10-12 gauge.
• Hardness: Higher than SS304, providing superior drilling power in tougher materials.

Usage:

• Heavy-Duty Metal Construction: Ideal for fastening thicker metals where strength is essential, such as in structural steel applications.
• Automotive Industry: Commonly used in vehicle assembly and repairs, especially where high strength is required.
• Machinery and Industrial Equipment: The Grade 410 screw is used to fasten components in heavy machinery or industrial equipment due to its high durability.
• Outdoor Construction: While its corrosion resistance is lower than SS304, Grade 410 screws are suitable for outdoor applications in moderately corrosive environments.
• Roofing & Cladding: Frequently used in roofing applications, particularly in areas where higher strength is required over corrosion resistance.

Key Differences:

1. Material and Corrosion Resistance:

   • SS304 BI-Metal Tek Screw: Features SS304 stainless steel body with excellent corrosion resistance, making it ideal for marine, outdoor, and highly corrosive environments.
   • Grade 410 Tek Screw: Made from harder, more durable Grade 410 stainless steel, which has lower corrosion resistance but offers higher strength, suited for moderately corrosive environments.

2. Strength and Drilling Power:

   • SS304 BI-Metal Tek Screw: Offers good drilling power, particularly in metal-to-metal applications, but with a focus on corrosion resistance.
   • Grade 410 Tek Screw: Higher tensile strength and hardness, allowing it to drill through tougher, thicker metals more efficiently.

3. Best Use Case:

   • SS304 BI-Metal Tek Screw: Best for environments where corrosion is a primary concern, such as roofing in coastal areas or marine structures.
   • Grade 410 Tek Screw: Best for heavy-duty construction tasks where strength and hardness are prioritized, like industrial equipment or automotive applications.

Both screws provide durability and reliability, but their specific strengths make them suitable for different types of projects depending on the environmental and structural needs.
