Treated Sill Anchor

Treated Sill Anchor

Treated Sill Anchor

Every other year (or so) I revisit this issue to see if there is a better way.

Ever since the preservative treated wood corrosion awareness several years ago, I have specified the Rawl Stainless Steel Spike 3/8 x 4", to fasten the sill plate to concrete.  During the past couple years, this item has been discontinued and no longer available.  I now specify the Rawl SS Power-Stud to obtain the desired concrete embedment to prevent uplift.  I dislike this product for this application, in comparison to the latter, simpler, installation of the spike.  Hilti and Wej-it/Ankr-Tite do not make a spike.

I am aware that the 2003 IRC allows >=1/2" (non-stainless) carbon-steel steel bolts to be used with pressure treated lumber, (due to assumed adequate size, that will not corrode through) but, this is not acceptable at the Wisconsin Commercial approval level.

Is there a better sill anchor?

Is there a better system?

Thank you ...

RE: Treated Sill Anchor

they specialize in this type of anchor.  I have attended a number of their seminars in Jacksonville, which are free by the way and you get ceu's for them.  They also have seminars in Texas and I believe Calif. Most of their anchors that come in contact with the new treated lumber can be spec. with a  "Z Max" coating which has 1.85 oz. of Zinc per sq. ft of surface area which is double what a standard G90 coating has.  These are the only anchors I use.  Hope this helps.  I dont believe they have a spike, but have had no complaints from contractors using their products.

RE: Treated Sill Anchor

I would contact Simpson see if they would reccomend the use of a Titen HD screw anchor. Also I would use stainless steel or hot-dipped galvanized fastners in applications where they are in contact with ACQ treated wood.

We typically spec galvanized bolts for P/T connections.  Simspon is making thier Kwik Bolt III with a galv. coating
