These screws from Bremick are made specifically for decking and more outdoor projects. Its B8 coating makes it so that you can rest easy that these screws will last a long time securing your decks. B8 coating is a hard, highly abrasion and extremely scratch resistant alloy, which is eight times more durable than conventional, soft and friable, zinc and galvanised coatings. Its bugle head makes it so that the timber doesn’t split when countersinking. The ribs under its head allow this screw to cut the countersink themselves as you drive them in. These also have a type 17 point which allows self-drilling when using these screws. These screws are built thick making it ideal for a variety of applications from light to heavy carpentry.
