What is the best way to attach eye bolts and other hardware to Precision Board?
Since PB is a cellular material it is not recommended to screw hardware directly into it. The hardware, being metal, will expand and contract with temperature causing it to work its way back out. If excessive tension or pressure is applied to the fastener the treads will pull out of the cellular material. The most secure way to install a fastener or hardware is to drill a hole into the PB that is twice the diameter of the fastener and about 1/4″ deeper than its screw length. Fill this hole with a structural epoxy like EP-75, insert the fastener and let it cure. This way the threads are pulling against the hard epoxy and the epoxy is totally bonded to the inside of the hole. Check out the Mounting and Strengthening Data Sheet.
