Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Component Fastening with Spring Action: Designed to fasten and stabilize critical hardware components (e.g., graphics cards, CPU radiators, motherboards) while absorbing vibrations and impacts via integrated springs.
  • Multi-Material Construction: Offers materials like 304 stainless steel, titanium, and aluminum to cater to corrosion-resistant, lightweight, or high-strength requirements in diverse environments.

Key features

  • 1. Advanced Material Technology

  • With 304 stainless steel construction and zinc plating, these bolts resist corrosion and maintain structural integrity in high-heat environments. The titanium and black oxide-coated variants offer ~30% higher corrosion resistance than uncoated steel*, ensuring longevity in demanding electronic setups.

  • 2. Precision Spring-Loaded Design

  • With an integrated spring mechanism and threaded bolt system, these fasteners provide adjustable tension for secure mounting under thermal expansion or vibration. The spring design dampens shocks by 40% compared to rigid bolts*, safeguarding sensitive components like GPUs and CPUs.

  • 3. Versatile Performance Parameters

  • With thread sizes ranging from M1.6 to M10 and lengths up to 90mm, these bolts accommodate diverse cooling components (e.g., radiators, heat sinks). The 12+ size options ensure compatibility with 50% more hardware configurations than standard screws*, fitting both metric and inch systems.

  • 4. Optimized for High-Performance Scenarios

  • Designed for PC radiator mounting, these fasteners ensure stable heat dissipation under continuous operation. The washer-and-spring combo maintains optimal thermal contact, reducing interface failure risk by 25% in overclocked systems* compared to non-spring designs.

  • 5. RoHS Compliance for Safe Electronics Use

  • Certified to RoHS standards, these bolts eliminate hazardous materials like lead and mercury, ensuring safe integration into electronics. This meets EU regulatory requirements for environmentally friendly components.

Supplier's note

  1. Technical Breakthroughs:

    • Titanium Pro Model: 50% lighter than stainless steel while maintaining 3× higher corrosion resistance, enabling aerospace-grade durability in compact PC builds.
    • Variable Spring Load: Adjustable stiffness allows users to fine-tune vibration damping for GPUs under heavy gaming loads.
    • Thread Design: Tapered threads (M1.6–M10) provide 20% stronger grip in aluminum radiators compared to standard bolts.
  2. Version Selection Guide:

    • Base Model: Ideal for standard desktop builds (e.g., home PCs) where cost-efficiency is prioritized.
    • Advanced Model: Best for industrial or humid environments (e.g., server farms) needing corrosion resistance and moderate load capacity.
    • Pro Model: Suited for extreme applications like overclocked gaming PCs or robotics, where lightweight, high-strength, and thermal stability are critical.

With titanium’s thermal conductivity, you can ensure efficient heat dissipation in high-end gaming setups. The Pro model’s MIL-STD certification guarantees reliability in harsh conditions, such as automotive or aerospace electronics. Pair the Advanced model’s spring load with its stainless steel body to reduce component wear in 24/7 server operations.
