In furniture making, wood screws are used to assemble frames, attach legs, and secure hardware. Flat head and countersunk screws are often preferred to ensure a smooth finish, while brass or decorative screws can enhance the furniture’s appearance. Coarse thread screws work well with softwood furniture, and fine thread screws are better for hardwood pieces.

Cabinetry

Cabinetry relies on wood screws for joining panels, installing shelves, and attaching doors. Trim head screws are ideal for trim work and molding on cabinets, as they are less noticeable. Stainless steel or zinc-plated screws are commonly used to resist corrosion in kitchen and bathroom cabinets, which are exposed to moisture.

Holzbearbeitung

Holzbearbeitung projects of all kinds use wood screws. From small crafts to large wooden structures, the right wood screw ensures a strong and durable bond. Self-tapping screws are convenient for quick assemblies, while fine thread screws are better for precise work with hardwoods.

Konstruktion

In Konstruktion, wood screws are used in various applications, such as framing, installing flooring, and attaching trim. Coarse thread screws are often used for framing with softwoods, providing strong holding power. Stainless steel screws are suitable for exterior construction projects to withstand the elements.

Deck Building

Deck building requires wood screws that can withstand outdoor conditions. Stainless steel screws are the top choice due to their excellent weather resistance Und Korrosionsbeständigkeit. They secure deck boards, Schienen, and posts, ensuring the deck is safe and durable.

Bodenbelag

When installing flooring, wood screws are used to attach floorboards to joists. Countersunk screws are often used to ensure the heads sit flush with the floor surface, preventing tripping hazards. Fine thread screws are suitable for hardwood flooring to avoid splitting the wood.

Trim Work

Trim work involves attaching molding, baseboards, and casings, where the appearance of the screw is important. Trim head screws and oval head screws are commonly used, as they blend in with the trim. Brass or painted screws can match the trim color for a seamless look.
