The Bremick Hex Head Screws are used for joining metal to metal which usually requires greater strength and torque input. This type of hex head screw is ideal for when a watertight fastening is required. These screws have a type 17 point which allows self-drilling when drilling into wood. Its B8 coating makes it so that you can rest easy and that these screws will last a long time securing your projects. 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.
