Countersunk Head Wood Screws
Product Overview
The Demi Countersunk Double Color Taper Fiber Board Screw is a high-performance self-tapping screw specifically designed for panel fastening applications. Featuring a full-thread design with a color zinc surface treatment, it accommodates a wide range of indoor connection needs, from thin sheets to thick timber. Manufactured from a carbon steel substrate and hardened through heat treatment, it combines high hardness with excellent toughness, making it a cost-effective premium alternative to ordinary wood screws in furniture assembly and woodworking renovation.
Product Applications
Furniture manufacturing: Assembly and connection of panel furniture such as wardrobes, cabinets, tables, and chairs, and display cases; compatible with mainstream panels including medium-density fiberboard (MDF), particleboard, and plywood.
Renovation and construction: Indoor timber partitioning, ceiling substructures, timber joist installation, and decorative panel fixing—suitable for panel splicing and load-bearing connection requirements.
Woodworking DIY: Various handmade woodworking projects, shelving units, storage boxes, and other custom builds; adapts to soft and medium-hard woods such as pine and poplar, enabling quick installation without complex pre-treatment.
Warehouse shelving: Panel splicing and fixing for light-duty wooden shelves and storage racks, balancing connection strength with installation convenience.
Product Features
Split-resistant double countersunk head: Assists in pilot-hole expansion during driving, reducing the risk of panel splitting; the head can be fully countersunk, leaving a flush and aesthetically pleasing finish after installation.
Full-thread strong-grip thread: Provides a large thread engagement area for excellent pull-out resistance, ensuring secure and stable connections that resist loosening.
Color zinc anti-rust coating: Delivers superior rust prevention, resisting corrosion and discoloration in indoor use, while protecting panels from surface staining.
High-hardness substrate: Heat-treated hardened carbon steel resists breakage and stripping, making it compatible with power tool installation.
