Self-tapping screws tap their own threads in the material but usually require a pre-drilled pilot hole. Self-drilling screws feature a point shaped like a drill bit, allowing them to drill, tap, and fasten in a single operation without pre-drilling.

Truss head wood screws feature a wider, slightly rounded head with a larger surface area. This low-profile design provides excellent holding power, reducing the risk of the screw head pulling through thin materials or softwood.

These specialized screws are designed to securely attach plasterboard layers together. They feature coarse threads that grip the gypsum cores tightly, ensuring a strong, flat connection that prevents joint cracking or shifting.

Stainless steel offers superior resistance to rust and environmental corrosion. Stainless steel self-drilling screws are ideal for outdoor construction, marine environments, and applications exposed to moisture or chemical agents.

Round head wood screws are ideal when a decorative finish is desired or when fastening hardware parts where the screw head needs to sit prominently above the wood surface without recessing.
