Double End Wood Dowel Screw
This double-ended wood screw is a dedicated fastener for splicing two wooden workpieces together, widely applied in furniture manufacturing and solid wood assembly.
It is integrally forged from carbon steel with blue white zinc electroplating finish, forming a compact anti-corrosion film to avoid oxidation in indoor furniture environments. Both ends are designed with deep coarse self-tapping wood thread and sharp conical tips, which can cut into two separate wood boards simultaneously to form tight splicing joints.
A flat hexagonal driving section is reserved in the middle of the screw shank, allowing users to clamp with open-end wrenches for convenient tightening operation, effectively solving the slipping problem of smooth double-head studs during installation. The deep thread teeth bite into wood fiber evenly on both sides, providing excellent anti-pull and anti-loosening capacity to prevent furniture splicing gaps after long-term use.
Unlike single-head lag screws, this double-ended design achieves invisible internal connection without exposed bolt heads on furniture surfaces, improving product appearance. All finished double end wood screws pass pull-out force and torsion resistance tests before delivery, complying with furniture hardware fastening standards. Custom lengths and alternative surface treatments can be produced for bulk furniture factory orders.
