What size are the toerail nuts?

[Jim Logan]

Recent rains have reminded me I need to tighten the bolts holding the deck, toerail, and hull together. I know you need a big screwdriver and a helper for the deck side, but what size are the nuts? I know it takes a verrrry deep socket. I'm not close to the boat today but want to make a Home Depot run> 1/2, 9/16?THanks

A deep 7/16" on the H37C.

Some of those nuts are in really hard to reach places. Along with a 7/16" deep socket you might want a couple of extensions. Also a universal or two, one of those flexible extensions would be good. You could confirm the 7/16" with a call to Hunter.
