Steel Deck Fastening Systems
SLC Sidelap Connectors for Fastening Deck-to-Deck 1.5
1.5.1 Product Description
The Hilti sidelap fastening system
consists of a stand up tool (SDT 5),
an electric screwdriver (ST 1800) and
collated sidelap connectors.
For nestable steel deck profiles, the tool
of choice is the SDT 5. It uses the ST
1800 electric or ST 1800-A18 battery
screwdriver to drive sidelap connectors
through sidelaps ranging from 16 to
26 gauge in thickness. Featuring an
adjustable torque clutch, the ST 1800
or ST 1800-A18 helps ensure proper
fastening while minimizing overdrive.
1.5.1 Product Description
screw driver provides for a completely
stand-up and cordless deck attachment. 1.5.2 Material Specifications
1.5.3 Technical Data
When compared with fastening
individual, non-collated, screws, the
SDT 5 offers the installer the capability
to work upright. By improving the
comfort and health of the installer,
productivity remains high all day,
helping keep the project on time and
on budget. 1.5.4 Ordering Information

1 Based upon attachment of two-same thickness layers of ASTM A1008 or minimum ASTM A653 SQ33
steel deck.
2 Allowable capacities based on a safety factor of 3.0.
3 Allowable tension capacities based upon the controlling capacity of pullout, pullover or fastener tension
strength.
4 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.
5 Allowable shear capacities calculated according to Section 4.5 of SDI DDM03 for standard No. 12 screw.
For shear capacities when used in diaphragm applications in combination with Hilti deck frame fasteners,
reference Q s values in Table 8 in Section 1.1.8.
6 Allowable shear capacities calculated according to Section 4.5 of SDI DDM03 for standard No. 10 screw.
