More info

A TD HEX RW SCREW WITH CUP WASHER is a specific type of self-drilling screw primarily used in construction, often for securing roofing and cladding materials.

Here's a breakdown of what the name typically means:

TD: This often stands for Tapping Drill or simply refers to a manufacturer's product line of self-drilling screws.

HEX: Describes the head type, which is a Hexagon (six-sided) shape, requiring a hex socket driver to install.

RW: This stands for Rubber Washer (or sometimes Bonded Washer). This means the screw is supplied with a washer that has a vulcanized rubber layer bonded to a metal backing. This washer is essential for creating a weather-tight seal against the material (like a metal roof panel) to prevent water leakage.

In other contexts, a cup washer is a separate decorative piece, but here it's typically referring to the Hexagon Washer Head combined with the rubber seal.

Key Features and Use
Self-Drilling: These screws have a drill-bit point, allowing them to drill their own hole and tap their own threads in one operation, saving time.

Sealing: The rubber washer is critical; when the screw is fully driven, the washer compresses to seal the hole, protecting the joint from water and dust.

Applications: They are widely used for fastening:

Metal roofing sheets (e.g., corrugated or trapezoidal profiles).

Metal wall panels (cladding).

Attaching metal to wood or metal framing.
