This is a PL-259 solder on connector for RG8 coax cable.  It is constructed of nickel plated zinc with a nickel plated brass center pin and Bakelite insulator.

This connector will only fit RG8 and LMR400 cable with a 0.405" diamter and you would need a reducer (not included) to use it with a smaller diameter cable like RG8X/Mini 8.
