High Tensile Countersunk Screws Yellow Passivated | Duchy Fasteners

Sold in boxes of 100.

Engineered for demanding professional use, this range of high-tensile countersunk woodscrews delivers exceptional strength, reliability and a clean, flush finish. Manufactured from robust high-tensile steel, they provide superior load-bearing performance, making them ideal for structural applications where secure, long-lasting fixings are essential.

The recessed drive (including both traditional and Pozi styles within the range) ensures excellent torque transfer and reduces the risk of cam-out, helping to achieve fast, efficient installation with power tools or hand drivers. The countersunk head sits neatly below the surface of the material, giving a smooth, snag-free finish that is perfect for visible or finished work.

A durable passivated coating enhances corrosion resistance, offering added protection in environments exposed to moisture, wear and changing conditions. This makes these screws suitable for use in construction, timber framing, joinery, mechanical engineering, machinery assembly and even certain automotive and maintenance tasks where a strong, corrosion-resistant fixing is required.

Available in a wide selection of gauges and lengths, this range allows you to choose the right combination for everything from fine detail work to heavy-duty structural connections. Whether you are fixing timber to timber, installing hardware, or completing interior and exterior projects, these high-tensile countersunk screws are designed to deliver consistent, professional results.
