Installing screws and other threaded fasteners with WEST SYSTEM epoxy dramatically improves load carrying capacity by spreading the fastener’s load into a greater area of the substrate. There are several methods or levels of hardware bonding depending on the loads on the hardware.
Basic fastener bondingFor improved pullout strength and waterproof connections, the easiest fastener bonding method is to simply wet out stripped fastener holes and new pilot holes before installing the screws. Epoxy penetrates the fibre around the hole, effectively increasing the fastener diameter. Epoxy also provides a stronger interface with the fastener threads than wood fibre and keeps out water.
- Wet out a standard-size pilot hole. Work the mixture well into the hole with a pipe cleaner or syringe. Thicken a second coat of epoxy as necessary for stripped or oversized holes.
- Insert the fastener in the hole and allow the epoxy to cure.
