    Comments about MASTER LOCK COMPANY Master Lock Magnum Disc Padlock (M40XTCCSEN):

    I use it on a storage unit.

    I am not bashing Master Lock or the employees who make them... The lock is very adequate, but not perfect. There is some room for improvement in measuring and cutting the stainless and the working mechanism inside the lock when it is rotating to the lock position.

    When closed the lock is more than good enough to use and keep. I won't return it!

    I looked up Carbon Boron and I am amazed that is is actually a byproduct of steel refining and the 3rd hardest substance known to man.
    I think it is a good way to use the byproducts of manufacturing and reduce waste. Kudos to Master Lock for turning trash into something to protect a treasure!


    I was disappointed these are not individually keyed

        I was disappointed these are not individually keyed. The box had five locks with the same key. There maybe people who want all their locks keyed the same but if I'm buying individual locks I prefer them to be uniquely keyed.
