1 Steel base material strength (F u ) shall be in the range of 58 to 91 ksi for base steel thicknesses (t f ) less than or equal to 5/16". For base
steel thicknesses greater than 5/16", the tensile strength shall be in the range of 58 to 75 ksi.
2 The X-HSN 24 and Racing Tip Fastening Systems will fit in all deck types except A-deck.
3 This fastener can be used with structural steel within the thickness ranges shown.

2 Other sidelap connector types are possible with Hilti’s powder actuated frame fasteners. Please reference the Steel Deck Institute (SDI)
Diaphragm Design Manual 3rd Edition (DDM03).
3 Use of S-SLC 01 M HWH with 18 gauge steel deck is recommended only for standard tensile strength (45 ≤ F u ≤ 65 ksi) steel deck.
For high tensile strength (F u > 65 ksi) 18 gauge steel deck, use S-SLC 02 M HWH.
Sealing Caps
The SDK2 is an SAE 316 stainless steel sealing cap with a
neoprene seal. This is installed over the head of the X-ENP-19
fastener using the SDK2 hand setting
tool. The SDK2 sealing cap provides
added corrosion protection for exposed
exterior steel deck applications in
SDK2 Setting Tool
accordance with IBC requirements.

h nvs = 8.2 mm- 9.8 mm
Note: The sealing cap and fastener must be installed correctly to achieve a water-resistant seal. Contact Hilti for details.
