VEVOR Umbrella Base, 24" Square Umbrella Base, 32lbs Umbrella's Holder Stand, Cast Iron Umbrella Base for 1.5-1.875" Umbrella Pole Market Umbrella Base with 14" Height Pipe for Yard/Garden/Deck
Is the screw that connects the flat base to the pole holder welded in place or does it go through the flat base? I'd like to replace the screw with a Grade 5 screw.
