Zombie Apocalypse: Free reign over a big box hardware store. What do you do?

Okay, it’s the zombie apocalypse, and since you were smart enough to put together your survival kit ahead of time, you managed to survive for at least a little while. Congratulations! You and your plucky band of nomadic survivors find yourselves at a big box hardware store like Home Depot or Lowes, and miraculously it’s mostly untouched. After clearing out all the snack food impulse buys at the front and the snacks in the employee lounge, what do you do? What could you cobble together from the contents of a hardware store?

Let’s assume you have at least a week before more zombies find you and you have to fight them off or flee.
