The 6 digit ITW Plexus lot number represents the date of manufacture code for our products.
The breakdown for lot 001051 is as follows:

110253 will be the third batch produced on October 25, 2011


Note 1 : Our lot codes will repeat by decade but our shelf life maximums are less than two years so there will not be any conflict in use by dates.
Note 2: While we do put a shelf life expiration time from date of manufacture, many of our products will perform well past their shelf life, especially when stored in cool conditions. Please see the TDS for recommended storage conditions. We recommend a simple cure test at your location if you are in doubt.
