100mm screws

100mm screws are typically used where a strong, secure fixing is needed for deeper materials. You'll find them in structural timber framing, decking, and stud wall construction. Builders often use 100mm wood screws for joining large timber sections, especially in roofing and floor joists. In concrete work, 100mm concrete screws offer a quick fix for securing battens, sole plates, or formwork. They’re also common in drylining where extra length is needed, such as with insulated plasterboard or complex layering.

Products in this category include multi-purpose screws, as well as specialised options like 100mm decking screws with corrosion-resistant coatings, or drywall screws with bugle heads for reduced surface damage. Compared to shorter or thinner fixings, 100mm screws provide higher pull-out resistance and greater stability across thicker materials. This makes them suitable for structural and external applications where durability and load bearing are critical.
