Introduction 1.1 Definitions and general terminology Hilti direct fastening technology is a technique in which specially hardened nails or studs are driven into steel, concrete or masonry by a piston-type tool. Materials suitable for fastening by this method are steel, wood, insulation and some kinds of plastic. Fastener driving power is generated by a power load (a cartridge containing combustible propellant powder, also known as a “booster”), combustible gas or compressed air. During the driving process, base material is displaced and not removed. In Hilti terminology, DX stands for “powder-actuated” and GX for “gas-actuated” systems. 1.2 Reasons for using powder or gasactuated fastening The illustrations below show some of the main reasons why many contractors take + + + = 2.4 kN= 2.4 kN ? + 1 Speed is important. An easy-to-use, uncomplicated fastening system is required. Electric power is not available or electric cables would hinder the work. 2 1 advantage of the benefits of powder or gasactuated fastening. 1.4 11 / 2007 1 2 ? 2 A weather-independent fastening system is required. + + = 2.4 kN
