Double Hook Metal Spring Continuous Length Extension Springs Custom Stainless Steel Tension Spring 3mm for Lawn Mower

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Tension Application: Designed as a double hook extension spring for lawn mowers and machinery, providing reliable tension with load capacities of 20lb and 40lb.
  • Durability & Versatility: Constructed from high-quality steel or stainless steel, featuring zinc plating for corrosion resistance, ensuring longevity in diverse environments.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With corrosion-resistant stainless steel and zinc-plated surface, ensure long-lasting durability in outdoor environments like lawnmowers. Stainless steel provides superior rust resistance compared to standard carbon steel, while zinc plating adds an extra protective layer.

  • 2. High Load Capacity for Heavy-Duty Use

    • With a maximum 40lb load capacity, handle heavy-duty applications more effectively than standard springs designed for lighter loads. This makes it ideal for demanding equipment like lawnmowers that require sustained force.

  • 3. Secure Double Hook Design for Easy Installation

    • The double hook design allows secure and easy installation, reducing setup time compared to single-hook alternatives. The hooks ensure stable attachment to machinery components, minimizing slippage or detachment risks.

  • 4. Custom-Tailored for Lawn Mower Applications

    • Custom-designed for lawnmower use, this spring ensures reliable performance in continuous operation scenarios. Its extension mechanism and load capacity are optimized for the repetitive stress of landscaping equipment.

  • 5. Flexible Continuous Length for Precision Customization

    • Continuous length design enables precise cutting to desired dimensions, offering greater flexibility than pre-cut springs. This allows users to tailor the spring’s length to fit specific machinery needs.
