Introducing Our Double Headed Traceless Nail: A Marvel of Modern Fastening
1. Core Definition and Structural Analysis
Discover the double head non-marking nail—a revolution in lightweight fastening technology. This advanced solution eliminates the need for drilling, offering repeated disassembly without hassle. The innovative design surpasses traditional nail and glue methods, merging a double-head collaborative mechanism with a flexible support structure for ultimate versatility.
The Ingenious Double Headed Anchor Design:
Main Nail Head (Mechanical Anchoring End): Ingeniously engineered with 3-6 high elasticity steel needles, each 0.3-0.8mm thick and extending 5-12mm in length, this head embeds radially into substrates. While only using 1/5 the contact area of traditional nails, it achieves unmatched mechanical interlocking through subtle substrate deformation.
Secondary Nail Head (Flexible Buffer End): Crafted from high-density polyurethane or silicone composite (Shore A 85-95 hardness), this 1-2mm layer acts as a shock absorber, minimizing substrate stress by adeptly cushioning vibrational impacts.
Modular Structure: Ingeniously designed for longevity, the main and secondary nail heads connect via detachable threads, allowing for easy replacement of damaged parts, thus prolonging the product’s service life.

Significance of Typical Parameter Values in Applications
Boasting a load-bearing range of 1-15kg in vertical load scenarios, our nails excel in supporting lightweight objects like decorative paintings and shelves with ease.
With a substrate thickness adaptation of 3-30mm, it seamlessly integrates with materials such as gypsum board, medium-density fiberboard, or lightweight brick.
Operate effortlessly by hand thanks to an installation torque of 0.5-2N·m, eliminating the need for additional tools and simplifying construction processes.
Experience minimal disassembly residue ≤ 0.1mm on substrate surfaces, making it ideal for rentals and decorative scenarios where aesthetics matter.
Capable of withstanding temperatures from -20 ºC to 80 ºC, it's perfect for diverse environments, including outdoor air conditioning units and northern heating setups.
Designed for durability, our nails offer cycle usage of ≥ 50 times under standard test conditions, significantly lowering costs per use.
3. Core Functional Advantages
• Unparalleled Multi-Scenario Compatibility:
• Adaptation to Soft Base Materials: Overcoming anchoring challenges with low-strength substrates like gypsum board and foam brick, thanks to a steel needle taper (15°-20°) and elastic layer synergy.
• Mastery of Curved Surface Installation: The secondary nail head’s flexible layer ensures adherence to substrate curvatures up to 5°, maintaining robust attachment.
• Advanced Dynamic Load Management:
Through rigorous vibration testing (10-50Hz frequency, 2mm amplitude), our steel needle and elastic layer 'spring damping' system dissipates over 70% of impact energy, minimizing fall risks.
• Commitment to Environmental Friendliness:
Galvanized steel needle surfaces (5-8 μm thick) withstand 48-hour neutral salt spray tests without corrosion, ideal for humid environments.
Crafted from biodegradable materials, our elastic layer complies with the EU RoHS 2.0 environmental standard, ensuring sustainability.
4. Typical Application Scenarios
• Transformative Home Decoration Scene:
Seamlessly replace traditional cement nails for photo frames and walls, preserving your walls from unsightly cracking.
Secure kitchen storage racks and bathroom towel racks with confidence, protecting delicate tiles from damage due to drilling.
