STAINLESS STEEL WOODSCREWS

Woodscrews

A Woodscrew is a threaded fastener designed to be driven directly into timber, using a sharp point and a coarse thread to cut its own path into the material and hold securely without a pre-formed nut or insert. The range covers multiple head styles, drive types and finishing options for general joinery, fixing and construction work in wood.

Materials
Woodscrews in this range are manufactured in stainless steel, offering better resistance to corrosion and staining than plain or plated carbon-steel equivalents, which makes them suitable for both internal and external timber work.

Countersunk Woodscrews
The Pozi Countersunk Woodscrews DIN 7997 and Slot Countersunk Woodscrews DIN 97 have a flat, tapered head designed to sit flush with the surface of the timber once fully driven, giving a neat finish for general joinery and fixing work.

Raised Countersunk Woodscrews
The Pozi Raised Countersunk Woodscrews DIN 7995 and Slot Raised Countersunk Woodscrews DIN 95 have the same tapered underside as a standard countersunk head, but with a domed top that sits slightly proud of the surface, often chosen for a more decorative or finished appearance.

Round Head Woodscrews
The Pozi Round Woodscrews DIN 7996 and Slot Round Woodscrews DIN 96 have a domed head that sits entirely above the surface, traditionally used with a cup washer or where the screw head is meant to remain visible.

Mushroom Head Woodscrews
The Hexalobular Mushroom Head Woodscrews have a broad, low-domed head giving a larger bearing surface than a standard round head, useful where extra clamping area is needed against softer or thinner materials.

Sealing Washer Woodscrews
The Pozi Raised Countersunk Woodscrews and Hexalobular Raised Countersunk Woodscrews are also available with 15mm, 20mm or 25mm bonded sealing washers fitted beneath the head, giving a weather-resistant fixing point for external timber applications.

Decking Screws
The Square Drive Decking Screws are designed specifically for fixing deck boards, combining a square drive for slip-resistant driving with a thread profile suited to repeated exposure to the elements.

FAQs
What's the difference between a countersunk and a raised countersunk head?
A countersunk head sits flush with the surface of the timber once driven, giving a completely flat finish. A raised countersunk head has the same tapered underside but a domed top that remains slightly proud of the surface, which is more of a finishing or decorative choice than a functional one.

How is a decking screw different from a standard woodscrew?
A decking screw typically has a coarser thread and a sharper, more aggressive point than a standard woodscrew, designed to drive quickly through deck boards and resist the swelling, contracting and repeated foot traffic that outdoor decking is exposed to over time.

What are the sealing washer sizes (15mm, 20mm, 25mm) for?
The bonded sealing washer sits under the screw head and compresses against the timber as it's driven, helping to close the fixing hole against water ingress. The different sizes accommodate different head styles and fixing loads, with the larger washers giving a wider sealing area.
