Helpful Answers About Your Lag Bolts and Washers
Clear details to feel confident installing and trusting your fasteners
Are these lag bolts rust resistant outdoors?
Yes. The hot dip galvanized finish protects the carbon steel from corrosion, extending the life of outdoor decks, fences, and pergolas.
Do washers come included with the bolts?
Yes, USS flat washers are included to spread load and prevent bolt heads from sinking into softer wood during heavy use.
What size pilot hole do I need?
Drill a slightly smaller pilot hole than the bolt core. For example, use a 3/16 bit for common 1/4 lag bolts to ensure tight threads without splitting wood.
Can these hold heavy loads like beams?
Designed for heavy-duty applications, these lag screws provide superior load-bearing capacity for connecting wood to beams, posts, and structural fixtures.
Are these easy to install for DIYers?
Yes. The hex head accepts a socket or wrench for straightforward driving, making weekend projects faster and less frustrating.

Try these hot dip galvanized lag bolts risk-free for 30 days. If they don't deliver stronger, rust-resistant wood connections or make installations easier, return them for a full refund. We want your deck, fence, or project to last—and to make DIY feel simple and reliable.

Used for a heavy door frame install, the hex head made it easy to torque properly, threads cut cleanly into wood, and the overall strength gave me confidence the frame won't sag over time.
