Product Description

Detailed Description of Plum Blossom Groove with Ribbed Rolling Flower Screws: Immerse yourself in the intricacies of our innovative screw design, tailored for unparalleled wood joinery excellence. Discover the artistry behind our premium solution.

Comprehensive Analysis: Explore an in-depth examination of structure, function, application scenarios, and technical parameters, unveiling the superior craftsmanship of our products.


1. Head Design: Precision-crafted Torx®/Star Shaped Slot – engineered for maximum efficiency and performance.

Functionality Overview: The hexagonal star-shaped groove, featuring a dedicated plum blossom head (ranging from T10 to T40), ensures powerful torque transmission. This advanced design significantly reduces tooth slippage, enhancing installation efficiency by approximately 30% compared to traditional single or cross grooves.

Anti-Slip Innovation: The groove is meticulously fitted with anti-slip ribs, ensuring stable bite even at the high-speed operation of electric tools (recommended speed ≤ 2500RPM), making it perfect for demanding conditions.

2. Thread Structure: Ribbed Knurled Thread – engineered for optimal performance and reliability.

• Rolled Thread Excellence: Featuring continuous circular protrusions, or ribs, on the thread surface, with an impressive 4-6 ribs per inch and rib heights between 0.1-0.2mm. This design enhances wood fiber grip, ensuring superior stability.

• Anti-Loosening Principle: Once embedded, the rolled rib forms a mechanical lock within the wood, increasing pull-out resistance by 50%-70% over ordinary wood screws. Ideal for vibration-prone environments such as furniture assembly and window installations.

3. Rod Material and Surface Treatment: Constructed from premier materials and coated for lasting performance.

• Material Selection:

Carbon Steel (C1022): Offers high hardness (HRC35-40), making it perfectly suited for softwoods such as pine and fir;

Stainless Steel (SUS304): Known for its exceptional corrosion resistance, ideal for outdoor or humid settings like garden furniture and bathroom cabinets.

• Surface Treatment Options:

Galvanized Blue and White Passivation: Provides outstanding rust prevention for indoor settings, proven by salt spray tests lasting ≥ 72 hours;

Dacromet Coating: Exceptional resistance to salt spray for ≥ 500 hours, making it the perfect choice for coastal or industrial areas with high pollution levels.
