Notes:

1. Capacities shown are for stone aggregate concrete and are based on a low velocity shot.

2. Minimum fastener spacing: 4"; minimum fastener edge distance: 3".

3. Values may not be increased by 1/3 for wind or seismic loads.

4. ICBO uninspected values - Hilti/ICBO research #2388.

Notes:

1. Tests were conducted with the fastener point driven completely through the back side of the hot-rolled steel member. This

was necessary to obtain proper gripping force.

2. Fasteners should not be located less than 13 mm (1/2") from the edge of steel.

3. A minimum fastener spacing of 38 mm (1-1/2") is necessary.

4. Bearing strength based upon: 1.15(228 MPa)(Bearing Area) [1.15(33ksi)(Bearing Area)] for cold-formed steel.

5. Capacities shown are for either shear or pullout.

6. Values may not be increased by 1/3 for wind or seismic loads.
