I have 18 gauge deck and I am using the Hilti product X-ENP-19 to fasten it to a W200x22 beam (W8x15) of a length of 1675mm (5-1/2') and I'm trying to figure out how close I can space the fasteners and what is the maximum capacity I could get along this length in shear on the anchors.
Hi,
Apologies for the delay in response. Due to technical difficulties the question was not visible to us. Kindly review the technical details of our PAF systems in Hilti’s Direct Fastening Guide starting page 152 and page 186 for X-ENP 19 tables particularly. You can also review the ESR-2776 for more information. Also to help with your calculations, Hilti offers a very helpful tool, Profis Engineering design software available for customers to use. The software found under this link, is free in the standard version and offers additional features in the premium version. For decking fastening connection design, you can choose the Diaphragm Design module.
