Countersunk Head Wood Screws
Product Overview
This double countersunk Torx recess quick-thread wood screw covers diameters of 6–10mm and lengths of 16–32mm. It is manufactured from a high-quality carbon steel substrate with a colour zinc electroplating and passivation treatment on the surface, combining high strength with basic anti-rust capability. The product integrates three core design features—double-cone countersunk head, Torx internal drive, and quick-thread cutting geometry—making it an upgraded self-tapping screw specifically developed for fastening wood-based panels. Unlike traditional cross-recess fibreboard screws, it is suitable for batch installation with power tools and is widely used in furniture production, indoor woodworking renovations, preservative-treated wood construction, and similar applications, balancing installation efficiency, board protection, and finished product aesthetics. It performs reliably in both indoor environments and semi-humid balcony conditions.
Product Applications
Whole-House Custom Furniture: Assembly and fastening of wardrobes, kitchens, tatami platforms, tables, chairs, and panels;
Home Woodworking Renovations: Installation of floor joists, door frames, wall panelling, ceiling battens, and decorative trim;
Semi-Outdoor Wood Landscapes: Balcony preservative-treated wood trellises, terrace wooden decks, and garden fences;
Small Timber Structures: Stair treads, shelving frames, and various indoor wood component fastening.
Product Features
Double-Cone Countersunk, Flush and Anti-Splitting: Self-countersinking without pre-drilling, with the head fully embedded into the board surface for a flush finish; the double-cone design disperses compressive stress to reduce board splitting, while the thickened head resists damage during driving.
Torx Internal Drive, Efficient and Effortless: The recess ensures even force distribution, reducing bit slippage and wear; compatible with cordless drills for batch operations, enabling faster installation and fewer reworks.
Quick-Thread Coarse Thread, Secure Locking: Equipped with a self-cutting point for easy driving into both soft and hard woods; the coarse and deep thread provides strong bite force, excellent pull-out resistance, and anti-loosening performance, keeping panel joints tight without gaps.
Colour Zinc Coating, Cost-Effective Rust Protection: Double-layer passivation offers moisture and rust resistance with an attractive appearance; lower cost compared to stainless steel screws, making it ideal for large-volume procurement.
Comprehensive Specifications: Available in multiple diameters and lengths to suit various fastening needs, from thin decorative panels to solid wood frames and load-bearing timber sections.
