What type of lag bolts should I use for a deck?
You may not use electro-galvanized bolts for ledger or joist-beam attachments.

See IRC 502.2.2.1. Hot dipped or stainless steel only.

Electro-plated is also not appropriate for contact with treated lumber.

It may be that the bolts you listed are hot-dipped, but usually those magic words are listed, due to the code requirements.
