LEITE Computer PC Graphics Card M3x12mm Knurled Head Thumb Screws Black

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Adjustment: The knurled thumb screw enables effortless, thumb-driven adjustments for applications requiring fine-tuning, such as securing PC graphics cards, machinery components, or equipment settings.
  • Secure Fastening: Designed with a durable metal construction (steel, aluminum, or stainless steel), it provides robust hold in dynamic environments while resisting corrosion and wear.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a core of 304 stainless steel or corrosion-resistant alloys, these thumb screws ensure long-term durability in humid or chemically exposed environments. Superior to standard steel in resisting rust and oxidation*, they maintain structural integrity over time.

  • 2. Ergonomic Knurled Design for Precision Control

    • The knurled thumb-friendly head provides a secure, slip-resistant grip, enabling effortless adjustments even in tight spaces. This design offers 30% better tactile control compared to smooth-surface screws*, ideal for precision tasks like graphics card component alignment.

  • 3. Versatile Thread and Length Compatibility

    • With thread sizes ranging from M3 to M24 and lengths from 4mm to 150mm, these screws accommodate diverse hardware configurations—from delicate PC components to heavy-duty machinery. Suitable for 90% of common mechanical assembly needs*, reducing the need for multiple screw sets.

  • 4. Multi-Scenario Application Flexibility

    • Engineered for both home and commercial use, these screws excel in precision tech assembly (e.g., graphics cards) and industrial machinery. Their durability and customization options (e.g., black oxide or zinc-plated finishes) ensure adaptability across environments from compact desktop builds to server racks.

  • 5. EPR-Certified Sustainability

    • Certified to Germany’s EPR packaging standards, these screws prioritize eco-friendly materials and disposal practices. This certification ensures compliance with strict environmental regulations*, distinguishing them from non-certified competitors.

  • Notes:

    • Comparative hints (e.g., "30% better grip") are based on manufacturer testing unless noted.

Supplier's note

  1. Technical Breakthroughs:

    • The knurled head design improves grip by 30% compared to smooth-head screws, enabling precise adjustments without tools.
    • EPR_Germany_Packing certification ensures eco-friendly packaging, reducing waste by 25% versus traditional methods.
    • Customizable finishes (e.g., cadmium-plated) deliver 50% better corrosion resistance than uncoated steel.

  2. Version Selection Guidance:

    • Base Model: Suitable for general-purpose applications (e.g., office equipment) where cost-efficiency is prioritized.
    • Advanced Model: Ideal for industrial machinery or outdoor use, where corrosion resistance and higher load capacity (e.g., in automotive parts) are critical.
    • Pro Model: Choose for extreme environments (e.g., aerospace, high-temperature furnaces) where titanium’s lightweight strength and thermal stability are required.

With the Pro Model’s titanium construction, you can withstand temperatures up to 200°C—30% higher than stainless steel—ensuring reliability in harsh industrial processes. Pair its blue anodized finish with chemical-resistant coatings to protect against aggressive solvents.
