Steel Deck Fastening Systems
X-ENP-19 for Fastening Deck to Structural Steel 1.3
1.3.1 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 860-ENP-L
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 collated strips
of 10. Four of these strips are loaded into
the DX 860-ENP-L tool along with the
cartridge strip, and enable the operator
to fasten at a rate of up to 1,000 quality
fastenings per hour.

These values represent testing performed in ASTM A36 plate steel.
The values must be compared with allowable tensile pullover values.
Allowable values based on safety factor of 5.0.
Allowable values are based on minimum 1/2" penetration depth through or into base steel. For 3/8"
penetration depth into 1/2" and thicker steels, reduce the allowable load capacity to 635 lb (2.79 kN).
