Deck fasteners at sloped deck
My joist is running perpendicular to roof slope. Joists are at 6'-0'' o.c max & deck is at 1/4'' per foot of slope. Can Hilti fasteners be attached to joist directly or we need to provide shim plate. See below sketch

Hi Shahadat,
Thank you for reaching out. In general, the use of two materials instead of one solid base material would be outside of Hilti’s published testing. Additionally, Hilti’s fasteners are not intended to be installed with a gap in between the steel base material and the deck and are intended to be installed perpendicular to the base material. More on this can be found in Section 3.5.1.2.4 of the Direct Fastening Product Technical Guide. 
Regards,
Katelyn
