Bugle Head Wood Screws
Product Overview
This product, available in specifications 14-10×50-200, is manufactured from carbon steel with a colorful zinc passivation coating. It features a bugle countersunk head with a T40 Plum Blossom (hexalobular) drive, coarse threads, and a sharp-pointed self-tapping tip, with lengths covering 50–200mm. As a heavy-duty wood-specific fastener, it can be driven directly into wood without pre-drilling, effectively balancing load-bearing capacity, rust resistance, and construction efficiency while offering high cost-effectiveness.
Product Applications
Home renovation: Fixing wooden joists for suspended ceilings and partition walls, subflooring, cabinetry, and plasterboard backing.
Landscaping: Garden preservative-treated wood boardwalks, planter boxes, patios, and landscape timber fences (non-coastal areas).
Timber structures: Purlins in wooden cabins, splicing thick timber, and composite connections between wood and light-gauge steel.
Others: Solid wood furniture, commercial display shelving, building formwork backing timbers, and various other wood load-bearing fastening applications.
Product Features
Bugle countersunk head: Sits completely flush with the panel surface when tightened, reduces edge blow-out, ensures a smooth finish, and minimizes the need for touch-up work.
T40 Plum Blossom (hexalobular) drive: Provides even stress distribution, delivers high torque without stripping, and offers basic anti-tamper properties.
Coarse shank and coarse threads: 14# thick shank combined with 10 coarse threads delivers strong holding power, suitable for thick wood and load-bearing components.
Sharp-pointed self-tapping tip: Built-in cutting edges eliminate the need for pre-drilling, enabling smooth driving even in long lengths with reduced risk of breakage.
Colorful zinc plating: Offers durable rust resistance for indoor and semi-outdoor use, with significantly lower cost compared to stainless steel screws.
Multiple size options: Full range from 50–200mm accommodates thin panels, joists, and heavy timber components.
