1 For use with all types of nestable deck or screwable interlocking deck .
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 .
