DataNumen Zip Repair is a free utility that allows for the repair and recovery of damaged or corrupted data from ZIP and self-extracting files.

DataNumen Zip Repair will quickly scan the Zip archives and recover as much of your data as possible, minimizing the loss caused by any file corruption. The process is simple, load the corrupted/damaged zip (drag n' drop is supported) and hit the Start Repair button. There are a few included tools available from the Options menu. These tools allow you to adjust incorrect data size, perform cross-reference information checks, and scan backward to see if more data can be recovered.

DataNumen Zip Repair does not have a fancy super modern interface like other apps. But what it lacks in looks is that it makes up for functionality and usability - a nice addition to any users toolset.
