Frequently Asked Questions
How many nails?
Up to (41) 0.131 in. nails, or #9 Strong-Drive SD connector screws.
Can I use it on a pressure-treated deck?
Not this finish. G90 galvanizing is for dry, interior framing. For preservative-treated lumber or exterior exposure, Simpson calls for ZMAX, hot-dip galvanized or stainless steel connectors and matching fasteners. Ask us about the ZMAX or stainless version.
