Hi Pete THe Tool you require is a Ko-ken 3020-100M10 in 3/8" drive or a
4020-100M10 1/2" drive, The correct name for the fastener is XZN, it is nothing like Torx, and there is no such fastener as a "star" this is a name used buy cheap tool companies to replace the name Torx as they do not have a licence to make Torx or use the name Torx......- posted
