IMI Bolt Identification

[ecross27]

What markings, if any, are found on IMI Mfg. full auto bolts?

If there are markings on IMI bolts, do they differ between bolt sizes?

What manufacturer, to anyones knowledge, applied a number that appeared consistant with what a serial number should look like to bolts?

Thanks

IMI did mark some bolts. But they weren't very consistent in which ones or how. I've seen some that were marked with caliber. I've seen some that had serial numbers. Karl.
