3.5.3 X-ENP-19 FOR FASTENING DECK TO STRUCTURAL STEEL
3.5.3.1 PRODUCT DESCRIPTION
The Hilti structural steel deck fastening system consists of powder-actuated tools which are primarily used with one fastener : the X-ENP-19 L15 , which is available either collated or non-collated .
For most structural steel decking jobs , the tool of choice is the DX 9-ENP tool . This self-contained stand up decking tool is powered by 0.27 caliber long cartridges , which are loaded into the tool in strips of 40 . The cartridges drive the X-ENP-19 L15 MXR fastener ( collated version ) into almost any type of steel deck and base steel thicknesses greater than or equal to 1 / 4 ". These fasteners are available in

1 ASTM B633 , SC 1 , Type III . Reference Section 2.3.3.1 for more information .
3.5.3.3 TECHNICAL DATA collated strips of 10 . Four of these strips are loaded into the DX 9-ENP tool along with the cartridge strip , and enable the operator to fasten at a rate of up to 1,000 quality fastenings per hour .
Other tools include the hand held DX 76-MX , a semi-automatic magazine tool . Other configurations of the DX 76 include a single fastener guide variation of the tool for miscellaneous use .
Hilti X-ENP-19 steel deck fasteners comply with ANSI / SDI RD1.0 , C1.0 and NC1.0 standards .
