Carpenters Mate provides high quality, hardwearing and reliable screws to suit both domestic roof jobs as well as large construction projects.
Our flat screws are commonly used for warm roofing applications to secure OSB insulation and sub layers directly to joists in one go. The flat head will countersink directly into the OSB to leave a truly flat finish, ready for membranes or resin top coats.

Why use a Carpenters Mate screw?
As you’ll know well, the traditional way of joining two or more timbers involves drilling the hole, hammering a bolt, securing the joint with a washer and nut and securing to a high torque. If you’ve carried out your fair share of roofing projects, you’ll know how difficult to it is to access both sides of the timber and how limited the space is. If you’re looking to improve the efficiency of this process, why not try our range of roof screws? With a Carpenters Mate self-drilling screw, you’ll receive a free drive bit included with each pack and won’t require a bolt and washer, meaning you can quickly secure your timber structure with access to the joint from one side only. You’ll also user fewer tools and components.
