We are working on a 1930 16 ' OT square stern that was used in salt water and has corroded screws and bolts. With the machine screws either the head is toast or the screw breaks. The machine screws are 10-24 or 10-32 and 4 inches long. The only 4 inch ones that I can find are 1/4" .
I have used a 1/4" in the past by grinding the head to reduce the diameter and countersinking so it closely resembles the smaller machine screw but the slot is bigger and it doesn't look good.
Does anyone have a source for 10-24 4" silicon bronze machine screws?
