Flat head wood screws are designed to sit flush with or below the surface of the timber, making them ideal for countersunk applications. Round head wood screws remain proud of the surface, providing high clamping force and a decorative finish.

Stainless steel wood screws offer superior resistance to corrosion and rust. They are highly recommended for outdoor constructions, coastal locations, marine installations, and projects using treated lumber.

While self-tapping wood screws are engineered to thread directly into the material, drilling a small pilot hole is still recommended, especially in dense hardwoods, to avoid splitting the timber and to guide the screw straight.

Structural screws are heat-treated and manufactured from high-strength carbon steel. They are designed for heavy load-bearing structural joints (such as deck framing and ledger boards) and usually do not require pre-drilling.

Socket head wood screws provide a deeper drive recess, allowing for higher torque transmission without slippage (cam-out). They are popular in furniture assembly and heavy timber framing where precision and strong clamping are required.
