Bow Pulpit Railings Are Loose - Hex Key Size?

[Scott W.]

Just noticed that the front railings on the bow pulpit of my 1991 Seafarer 228G started to move a little when I stand on the pulpit. We sometimes use the pulpit to get on and off our boat when we pull into a marina, as the engine bracket causes the aft to be far away from the dock to disembark safely. None of my "standard" hex keys fit the hex screws at the railing hoop. Anyone know what size hex I should purchase?

Have you tried a metric set?

And use a heat gun to loosen up the set screws, they are readily rounded out if jammed then can ony be drilled out, the heat will soften the salt.
Heat it up enought until you smell metal!

And use blue locktite when going back.
It will seal the threads from salt.
