New garage doors installed questions about support

[jackal2001]

Just had my new doors installed and was wondering about the support of the entire door being held up by one screw on either track. Should this be reenforced or the nolt replaced by a heavy duty grade 8 bolt?

that's a normal install, there is a lot more shear on that bolt than you need

Standard Operating Procedure... literally millions of doors secured just like that.

No Worries.

Never seen em use a 1/4-20 tapper then drive a nut on. We drill and use 5/16" bolts. The fit in the punched angle the same. Still shouldn't be an issue

That screw isn't holding up the whole door. You have two screws in the back, plus whatever is supporting the door track in the front. The single screw is holding about 1/4 of the door. A really beefy door these days weighs a couple hundred pounds, so each screw is holding maybe 50 lbs. My cheap garage door weighs under 100 lbs.
