Have typically situations where steel to steel screw connection will have drywall in-between this is typical if a hard lid ceiling is provided in a rated room. Is there anything provided on the technical documents providing the effects drywall have on tension and shear strengths, then how to determine the allowable strength. Similar to OSHPD document. Right now having a problem getting stamps as they are requesting something from the manufacture
Hi Shea,
Unfortunately, Hilti does not have testing specifically for a layered condition with steel-drywall-steel. However, information on Hilti's self-drilling screw options can be found in Section 3.6 of Hilti's Direct Fastening Product Technical Guide.
If you have further questions, please reach out to hnatechnicalservices@hilti.com or give us a call at 877-749-6337.
Regards,
Ashley
