  • How will they save me time?

    Using FastenMaster screws is guaranteed to save you time fixing timber structures. Although traditional methods work and have been tried and tested, a FastenMaster screw revolutionises the way in which tradesmen work.

    With a FastenMaster screw, no pre-drilling is required, and all that is needed is a cordless drill, a FastenMaster screw and a drill bit – significantly fewer tools and materials than the traditional method. Simply drill the screw into two adjacent timbers and you’re good to go!


  • What application can I use the screws for?

    FastenMaster screws can be used for a range of applications, including laying flooring, decking, and loft conversions, constructing roofs and erecting fences. For tradesmen looking for an efficient way to complete any timber structure, FastenMaster screws are ideal for wood-to-wood connections

  • What makes a FastenMaster screw so strong?

    FastenMaster screws have been comprehensively designed and engineered to ensure they work time and time again. Each screw has been manufactured from carbon steel grade 1022 or 10B21 wire and have a proprietary finish. What’s more, these self-drilling screws have also been heat-treated to strengthen the shell of the screw whilst retaining ductility for flexibility.

  • Where can I buy the drive tool?

    There is no need to buy a separate drive tool. Each FastenMaster screw pack come with a free drive tool, saving your time and money. If you’re looking to buy additional drive bits please get in touch.
