Fasteners and ProWood
ProWood Micro and ProWood Micro CA interact with fasteners in a similar manner to CCA pressure-treated wood. Although it has the same basic active ingredients as ACQ providing protection to the wood, the micronized technology in ProWood Micro and ProWood Micro CA results in much improved corrosion performance. Corrosion testing shows that the corrosion rates for ProWood Micro and ProWood Micro CA fall between CCA and untreated wood.
Based on this data as well as our extensive evaluation of the technology behind ProWood Micro and ProWood Micro CA, our fastener recommendation for ProWood is the same as for CCA: use hot-dip galvanized, for example G60 connector plates, or other fasteners and connectors as recommended by building codes. Fastener manufacturers may also recommend products that work well with ProWood Micro and ProWood Micro CA.
Regardless of the outdoor fastener you choose, ProWood Micro and ProWood Micro CA will provide better performance than other available treated wood products.
