Product Description

Introducing the exquisite Plum Blossom Groove Ribbed Rolling Flower Screws - an in-depth exploration of their distinctive features and exceptional performance.

(A comprehensive analysis of structure, function, application scenarios, and technical parameters that sets this product apart.)


1. Head design: Ingeniously crafted with a Torx®/Star-shaped slot, blending aesthetics with functionality.

Function: The sophisticated hexagonal star-shaped groove design ensures superior torque transmission via a dedicated plum blossom head (available in T10-T40 specifications), significantly reducing the risk of slippage. Experience a remarkable 30% boost in installation efficiency compared to conventional single or cross grooves.

Anti-slip brilliance: Featuring grooves embedded with anti-slip ribs, these screws maintain impeccable bite stability, even at high velocities with electric tools (ideal speed ≤ 2500RPM).

2. Thread structure: Ingeniously engineered ribbed knurled thread for maximum performance.

• Rolled thread: Meticulously crafted with continuous circular protrusions (ribs) lining the thread surface, boasting 4-6 ribs per inch and an individual rib height of 0.1-0.2mm, providing an enhanced grip on wood fibers.

• Anti-loosening mechanism: Once the rolled rib is embedded within wood, it establishes a mechanical lock, boosting pull-out resistance by an impressive 50%-70% compared to conventional wood screws. Ideal for use in vibration-prone settings like furniture assembly and door/window installations.

3. Rod material and surface treatment: Elevating durability and longevity.

• Material options for varied needs:

Carbon steel (C1022): Offers remarkable hardness (HRC35-40), perfect for softwoods like pine and fir.

Stainless steel (SUS304): Proudly corrosion-resistant, making it perfect for outdoor or humid settings such as garden furniture and bathroom cabinets.

• Surface treatment offerings:

Galvanized blue and white passivation: Meets rust prevention standards with a salt spray test endurance of ≥ 72 hours, ideal for indoor applications.

Dacromet coating: Withstands salt spray for ≥ 500 hours, suitable for coastal or heavily polluted industrial zones.
