Even if you cut slightly off from square, the tabernacle fittings will square themselves when you fit them into mast.

Do not over torque, and I do not know what it should be. I used nylon insert nuts and made them just snug. The load of the shroud will be added to the load placed on the bolt by the nut. If it is a 10-24 grade 2 the proof load is 962 lbs each, clamp/working load is 723 lbs. Leaving 239 pounds to failure. 2 bolts gives 478 pounds but there is not any safety factor at that load. I think the shroud should be at say 250 pounds, so there is not much left for the wind load and from rocking at the dock. Being just snug, the shroud can apply 1446 pounds and still be in the working load range.
