H-S PST 114 Stock is the rear trigger screw hole threaded?

[Ramdiesel]

This is my first H-S stock. I have 3 BC stocks they just use the self tapping screws. I just received my H-S PST 114 was putting my bottom metal on. I got the two action screws in but it looks like the rear trigger guard screw hole is threaded? does anybody know what size it might be or where I can get a screw? Or is it even threaded?
Thanks

Most have a theaded insert for a 10-32 button head machine screw.
