The HECO-TOPIX-plus Part Thread Countersunk Screws are structural timber screws manufactured from hardened carbon steel with a bright zinc-plated A3K finish. Their partial-thread design pulls timber components firmly together, while the countersunk head finishes flush with the timber surface.
Designed for professional timber construction, these screws are suitable for timber-to-timber connections, internal joinery, staircase construction and general carpentry. The zinc-plated finish is intended primarily for dry internal or protected applications; select a suitable stainless steel or corrosion-resistant fixing where greater environmental exposure is expected.
HECO-TOPIX-plus part thread countersunk screws are designed to produce secure timber-to-timber connections. The unthreaded section allows the upper component to be drawn tightly against the supporting timber as the screw is driven.
Key features:
These structural wood screws are intended for timber-to-timber connections where a strong clamping action and flush countersunk finish are required.
Typical applications include:
Technical note: The required screw diameter, length, quantity, spacing, edge distance and embedment must be established from the manufacturer’s guidance and the project-specific structural design. Pre-drilling may be required in hardwood, dense timber or where reduced edge distances are used.
Technical note: Always use the latest manufacturer documentation and project-specific design when determining the required fixing specification.
