Hatch dogs diameter?
« on: January 28, 2018, 11:52:01 AM »
I have a few hatch dogs with cracked nuts and missing bolt & knob.  I am not at the boat and need the diameter of the dog screw.  I have 2 choices 3/8-18 or 5/16-18.  Could you check the size on your boat?

Thanks a bunch,
martin

Hi Martin,  the ones on my boat are 5/16, and 2.5" long including the knob.  I compared it with a normal 5/16 stainless bolt you can buy at a hardware store and it has the same thread.  The only difference is that these dogs have a pointed end as compared to the blunt end on a bolt.  Matthew.

Hi Matthew,  Thank you for your response.  This will really help me out.  I will pickup some 5/16 knobs and bolts.
