Master Lock Pro Pack Shrouded Padlock 6-Pack vs Master Lock 40THC Shrouded Disc Padlock

Both are the same Master Lock shrouded disc padlock, so the real difference is pack size: the Pro Pack gives you six locks, the 40THC pack gives you two. The shrouded stainless body and disc cylinder resist cutting, prying and weather, which is why owners use them on sheds, gates and storage units. Buy the six-pack if you have several things to lock or want spares keyed alike; buy the two-pack if you only need a couple.

  • Choose the Master Lock Pro Pack 6-Pack if you have several gates, sheds or storage units to secure and want matching locks or spares on hand.
  • Choose the Master Lock 40THC 2-Pack if you only need one or two locks and don't want extras sitting unused.

What reviewers say

Master Lock 40THC Shrouded Disc Padlock

Owners of shrouded Master Lock padlocks generally report they hold up outdoors and deter casual cutting. Complaints center on the shroud limiting fit and on keys being easy to lose.

What people mention
  • Shackle securityPraisedOwners say the shroud makes the shackle very hard to reach with cutters.
  • Weather resistancePraisedThe stainless body is reported to hold up through rain and winter without seizing.
  • FitCriticisedThe wide shroud does not clear some hasps and lock holes.
  • KeysMixedUsers find the keyed disc cylinder secure but wish more keys came with it.

Questions and answers

Which is better for a shed and a gate?
The two-pack covers a shed and a gate with one lock each. If you also lock a storage unit or trailer, the six-pack saves buying again later.
Are the locks in both packs the same design?
Yes. Both are shrouded disc padlocks with stainless steel bodies and keyed operation. The packs differ in count, not in lock type.
Which lasts longer?
They should wear the same, since the lock itself is the same design. Longevity depends on weather exposure and lubrication, not pack size.
Is the six-pack worth stepping up to?
Only if you have more than two lock points or want spares. For one or two uses, the two-pack does the same job with less left over.
Can all the locks in a pack use one key?
Master Lock keyed-alike sets let one key open every lock in the pack. Confirm the keying on the specific pack before you buy.
Is a shrouded disc padlock good outdoors?
Yes. The shroud guards the shackle from bolt cutters and the disc cylinder resists picking and drilling. Stainless steel handles rain and salt air better than plain steel.
