Like most people I did not know that the screws attaching my door hinges to the frame were less than an inch long. I did know that they along with my hinges were very corroded, looked terrible and I decided to replace both with stainless steel. I found the exact hinges for exterior doors with four holes for each hinge, with the same hole pattern in stainless and read several articles that recommended using three inch screws to secure them.I did not need to remove the doors to get the job done, instead I removed each hinge separately and used the longer stainless steel screws to attach them. Once the old hinge was removed, I drilled longer pilot holes to accommodate the much longer screws. As I did not have a 3" long drill bit, I used a 1/8" bit that extended out of the drill about 2 1/2", blew the dust out of the hole with compressed air and shot a bit of "Blaster" TDL Dry Lube into the hole to make inserting the screw into the wood easier without stripping the head. It worked like a charm and the lube made it much easier as I stripped a few screw heads trying to get a good tight fit when I first started without the Dry Lube. I first tried to get the screws locally but 3" screws in stainless can be quite costly and Amazon had the right product at a good price. Why 96 screws? I have two double doors, that's 24 screws per door x 4.I would definitely recommend replacing the screws in your door hinges to make them more secure, especially if you reside in a coastal area in the hurricane prone regions of the U.S. and stainless is definitely the way to go.
