I Am Looking For Some Tech. Info. About Std. Lag Screws,

That Someone Might Know Or Would Know Where I Find.

I Am Attaching L3x3x1/4 Steel Angles To The 1 1/2 " Face

Of Wood 2x6 Studs (#2 Southern Yellow Pine*)

Thru Bolts Can Not Be Used In This Application.

I Plan To Use Hex Head Zinc Plated Lag Screw (Grade #2) With Std. Flat Washer.

* = Assumed Type Of Wood Used For Framing In This Area

Here Is What Info I Need:

1. Is There A Minimum Embed Ratio (Diameter x _?_ = Min. Embed) For Lag Screws ?

2. The Shear (Lbs.) And The Pull-Out (Lbs.) For Lag Screws:

a. 1/4 " With Minimum 1 1/4 " Embed In Wood

b. 3/8 " With Minimum 1 1/2 " Embed In Wood

c. 1/2 " With Minimum 2" Embed In Wood

3. Is There A Maximum Embed Ratio,

That Would Make The Tension Of Lag Screw The Important Figure ?

Values Can Be The 'Ultimate Load' Or 'Safety Work Load'

And What The Safety Work Load Ratio Is ?
