Does anyone know of technical papers that document the strength of screws in 2 part epoxy? I'll need the data for a sign permit. The intent is to attach 72" z-clip rails ( the rails have screw holes) to 18lb hdu by drilling slightly oversized pilot holes for the screws into the hdu, filling the holes with the 2-pt epoxy and inserting the screw thru the z-clip screw hole into the 2-pt epoxy. I sent an email requesting the info to West Systems. Waiting their response.
Thanks , Roy Shimp
