Facom/USAG 84 Series 7pc Allen Key Set (with Foam module tray) - metric set includes sizes 3-4-5-6-7-8-10mm. The 5mm size seems to be the most popular and I had to steal the 5mm size from several sets to fill a large order last year. As such, the 5mm wrench in this set is the new 84TZSA series (the USAG version with the zinc plating). They fit the older foam trays but markings for brand and size are on the opposite side of the tool and not shown when placed in the tray. Limited supply at close out pricing.
