STAINLESS STEEL HEXALOBULAR FLANGED BUTTON TIMBER SCREWS WITH CUTTING TIP

Hexalobular Flanged Button Timber Screws with Cutting Tip — A flanged button head combines a domed, proud-sitting head with an integral flange beneath it — effectively a built-in washer face — so there's no separate washer to source or fit, and the flange spreads bearing load over a wider area than a plain pan or button head would on its own. That makes this screw suited to heavier timber-to-timber fixing rather than board assembly: decking substructure, fencing, and general outdoor timber construction, where a strong, self-washering head and solid holding power matter more than a decorative or flush finish. The cutting tip beneath the flange removes material as the screw drives in rather than displacing it the way a standard sharp point would, which lowers driving torque and reduces the risk of splitting in the dense or larger-section timber typical of structural and landscaping work — a real consideration when fixing near the end grain of a joist or into hardwood fencing posts. Hexalobular drive is essentially standard on a screw built for this kind of sustained, higher-torque outdoor driving, since it resists cam-out far better than Pozidriv or a slotted equivalent under repeated power-tool use. Because this screw is intended for exterior and structural timber work, stainless grade matters more here than on most board fixings: A2 (304-equivalent) handles typical UK weather and most treated softwood construction timber well. A4 (316-equivalent) is worth the extra cost for coastal fencing and decking substructure, ground-contact applications, or timber treated with higher-copper preservatives, where A4's added molybdenum resists the chloride pitting and crevice corrosion that A2 can eventually develop in more aggressive exterior conditions. Choosing gauge and length should reflect the structural load being carried and the thickness of timber being joined, leaving enough thread engaged in the receiving timber for a genuinely solid fixing rather than just enough to hold the pieces together superficially.

FAQs
What are these screws used for specifically?
Heavier timber-to-timber fixing where a strong, self-washering head is wanted, such as decking substructure, fencing, and general outdoor timber construction.

How does a cutting tip help in this application?
It removes material at the point rather than displacing it, reducing driving torque and the risk of splitting in dense or larger-section timber typical of structural and landscaping work.

How does a flanged button head differ from a pan or raised countersunk head?
A flanged button head sits proud with an integral wide bearing collar, giving greater load spread than a plain pan head and avoiding the need to countersink, unlike a raised or standard countersunk head.

Is this screw suitable for structural loads, or purely for decorative fixing?
It's built for genuine structural and semi-structural timber fixing such as decking substructure and fencing, not decorative work — gauge and length should be chosen with the actual load being carried in mind.
