Re: Ledger Board Bolts
The current generation of pressure treated lumber ACQ or CA use more copper in the formula. With regular steel fasteners the copper would cause them to corrode rapidly.
Galvinized treated fasteners can be used ...however .... the electro-plated ones have too thin of a coating and will eventually corrode. Using hot dipped galvinized fastenters will have a thicker coating and will resist corrosion far better...... or ... galvinized fasteners which are labelled "ACQ approved" can be used as well.
The ultimate choice are stainless steel fasteners.
Hope this helps.
