Timberlok or lag bolts on PT wood posts?


I'm getting ready to bolt some 4x4 PT posts onto my deck for the rails. Should I go with the Timberlok wood screws, or run a lag screw all the way through?

The posts are dried, and the deck is dried as well. But there is a chance I may have to do a few posts using brand new (wet) 4x4 posts.

Bolts, not lags.

Whoop...yep, meant to say bolt all the way through. Anyone have any preference/experience using Timberlock screws vs. lag bolts?

You should drill through the posts and use bolts with washers and nuts on support posts and railings railings

No screws! Through bolts only. Figures 24, 25, 26: http://www.lancova.com/deckinfo.pdf

Excellent info in that pdf file! Answers pretty much all my questions!

(I sure am glad I notched only two of my 4x4 posts!)

You'll want to be sure to get bolts approved for use with PT lumber.
