Samac Fixings Performance Exterior Screws – Silver Countersunk (Box)

Samac Fixings Performance Exterior Screws are designed for reliable fixing in outdoor and exposed environments. Featuring a silver countersunk finish, these screws provide a neat, flush appearance while delivering strong holding power for a wide range of external timber applications.

Ideal for fencing, decking frames, sheds, landscaping projects, and general exterior joinery, these screws combine durability with ease of installation. Supplied in boxed quantities, they are well suited to both trade professionals and serious DIY users.

Durable Exterior Performance

The silver corrosion-resistant coating helps protect the screws against weathering and moisture, extending service life when used outdoors. The countersunk head allows the screw to sit flush with the timber surface, creating a clean finish and reducing the risk of snagging.

Engineered for smooth driving and dependable performance, these exterior screws offer consistent results across softwoods and hardwoods commonly used in outdoor construction.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
