The Yankee Hill Machine VICTRA-12 jam nut secures a VICTRA-12 modular shotgun suppressor to its mount and the host shotgun (brand part no. YHM-1250). It is made in the USA by Yankee Hill Machine from 17-4 stainless steel with a Melonite finish. One is included with every VICTRA-12 mount, so this listing is for a spare or replacement. It is a small part, but a lost jam nut stops a build until you have another.
