Can someone educate me on the correct thread pitch for my TL3 bolt knob? Thanks. Yes I’ve tried some searching, and I get a lot of “it should be”. Someone that owns a TL3, and replaced the bolt knob with another TL3 knob, what is the correct pitch?
 
The older actions were one size, the newer actions are something different....If you want to be sure call Bighorn. Ray will answer your question.
On my newer TL3 I ended up getting the adapter that someone makes....Area419??? so I could use common knobs that I already owned and love.

Oh, and have your action's serial number ready when you call.
 
If you have an older action where the threads are integral and machined into to the bolt body the thread pitch is 5/16-24", if you have a newer action where there is a threaded rod that screws into both the bolt body and the bold handle (female threads on each) the thread pitch is 1/4-28".
