Need help understanding a screw size: . 250-14x0.91

I'm trying to track down this screw/bolt for an older Jeep sunvisor, and from what I've been able to gather online, the gauge/diameter would be 1/4", the threads per inch would be 14 (is that the same as an M14 screw?), and 0.91" is overall the length. Is that accurate? Thanks in advance!
