Carbon Steel Wood Screws
Product Overview
This double countersunk Torx recess fast‑thread wood screw is available in diameters from 6 to 10 mm and lengths from 16 to 32 mm. It is manufactured from high‑quality carbon steel with a yellow zinc electroplating and passivation finish, offering both high strength and basic corrosion resistance. The product integrates three core design features – a double‑taper countersunk head, Torx internal drive, and fast‑cutting thread – making it an upgraded self‑tapping screw specifically developed for timber fastening. Unlike traditional cross‑recess fibreboard screws, it is well-suited for power‑tool batch installation and widely used in furniture production, interior woodworking, and preservative‑treated timber construction. It delivers installation efficiency, board protection, and aesthetic finish, and performs reliably indoors as well as in semi‑humid balcony environments.
Product Applications
Whole‑House Custom Furniture: Cabinet assembly, wardrobes, tatami platforms, and splicing of tables, chairs and panels.
Interior Carpentry & Renovation: Floor joists, door frames, wall panelling, ceiling battens, and decorative trim installation.
Semi‑Outdoor Wood Landscaping: Anti‑rot timber trellises on balconies, decking platforms, and garden fencing.
Light Timber Structures: Stair treads, shelving frames, and various indoor wood component fastening.
Product Features
Double‑Taper Countersunk Head, Smooth and Crack‑Resistant: Self‑countersinks without pre‑drilling, with the head seating fully flush into the board surface; the double‑taper design disperses compression forces to reduce splitting, while the thickened head resists damage during driving.
Torx Internal Recess, Efficient and Effortless: Even torque distribution prevents bit slippage and wear; compatible with cordless drills for high‑volume work, speeding up installation and reducing rework.
Fast‑Thread Coarse Thread, Secure and Tight: Integrated cutting point easily drives into both soft and hard woods; deep coarse threads provide strong bite, pull‑out resistance, and anti‑loosening, ensuring panels stay flush without gaps.
Yellow Zinc Coating, Cost‑Effective Rust Protection: Double‑layer passivation resists moisture and corrosion, with an attractive appearance; significantly lower cost than stainless steel screws, ideal for bulk purchasing.
Comprehensive Size Range: Multiple diameters and lengths available to suit various fastening needs, from thin decorative panels to solid timber frames and load‑bearing lumber.
