Hello,

My bass boat has universal bases for the posts.. basically a hole that fits a non-threaded kingpin style post. I wanted to know if the 'threaded' versions are the same diameter as the 'non threaded' versions. Reason being, they're about 5 bucks cheaper.

Anyone know?

Thanks!

Both are 3/4"in diameter. The threaded version is longer than the non-threaded ones. The base usually has the threads at the bottom of the hole on quality craft. Either one will work fine. BUT loosing the seat and pedistal in rough water is more of a possibility though without the threaded type if your base has the welded nut on the bottom of the hole.

I have a universal non threaded base in the front of my boat. I bought it not realizing my seat poles were threaded. My poles were too long to sit properly in the base. I ended up getting a large screw driver and bashing out the bottom of the seat base so the threads would go down through. I haven't had a problem at all. I leave the seat in 24/7 even when trailering on the highway and have had no issues.

Thanks! Ya, mine don't have any bottom to them.. the hole goes right down and it's just open on the end. Guess I could add a nut if I wanted to.

Thanks!
