Product Applications
Panel furniture: Assembly of wardrobes, kitchen cabinets, bed frames, office desks, etc. – shorter lengths for fixing decorative panels, longer lengths for load‑bearing main beams.
Interior carpentry: Fixing of wooden joists, suspended ceilings, door frames, skirting boards, wall paneling, and other indoor wood substrate installations.
Shelving and wooden cases: Assembly of load‑bearing wood structures such as retail shelving, display cabinets, and storage wooden crates.
DIY projects: Assembly of solid wood ornaments, wooden boxes, small shelving units, and other handmade wood items.
Note: This product is suitable for dry or slightly humid indoor environments. For outdoor or high-humidity conditions, stainless steel screws are recommended.
Product Features
Coarse thread for strong fastening: #10 coarse diameter, single-start deep thread delivers excellent grip in wood and resists loosening; sharp pointed tip allows direct driving into panels, eliminating the need for pre-drilling in most wood materials. Full-thread design suits heavy-duty connections in thick timber.
Countersunk head for neat installation: 90° single countersunk head with cross recess is compatible with both electric drills and manual screwdrivers. After tightening, the head sits completely flush with the surface, leaving a smooth, snag-free finish.
Color zinc plating for rust resistance and high value: Uniform color zinc coating provides effective moisture and rust protection indoors, with a finish that complements wood tones. More economical than stainless steel screws, making it ideal for bulk production.
Hardened for durability: Through heat treatment, the steel is hardened to deliver sufficient torque strength, reducing the risk of breakage or stripping during power driving.
