The present invention is a lightweight impact socket having an aluminum or other light metal blank having a fastener end and a drive end. A high strength, heat-treated steel alloy insert is inserted into the fastener end of the blank and glued in place to yield a highly effective impact socket. A drive end insert can be inserted into the bore at the drive end to add strength to the drive end of the impact socket. A high strength, heat-treated steel alloy sleeve can be adhered to the outside of the lightweight blank to add further strength to the drive end of the impact socket.
