Obvious to who? How was I supposed to know they didn't thread the fucking hole to the bottom/all the way thru? I torqued it to spec and the rail was seemingly rock solid. The torque driver snapped at 20 inch pounds and the rail was solid. How was I supposed to know the fucking screw was bottomed out and only really giving me 8 inch pounds of compression on the fucking rail?
I suppose I could have got all Smarty Pants and measued the depth of the hole and the length of the screw to within thousandths but I failed. I didn't do that.
