Shelf Angle Bolt Torque

[mla163]

I am using a Heckmann 425 wedge insert and Heckmann 427 askew bolt to anchor a brick relief angle to a concrete slab.

The question arose as to how much to torque the nut. The manufacturer has no specs. The bolt has an askew head, so it will tighten as vertical load is applied, but I am reluctant to have the connection "snug" only.

Has anyone else run into this condition? What torque should I spec?

Snug, should probably work. All are really trying to do is keep the shelf angle tight to the wall so the bolt doesn't see any bending loads. You could tack weld the nut or damage the threads to keep it from backing off.
