THETAG 304 Stainless Steel Padlock vs Master Lock 40THC Shrouded Disc Padlock

Buy the Master Lock 40THC 2-pack if you want a proven brand and two locks for a gate and a shed. Buy the THETAG 304 stainless padlock if you want a lighter, fully stainless keyed lock with four keys for a locker, cabinet or bag. The Master Lock is a shrouded disc padlock, so its shackle is much harder to cut than the THETAG's exposed shackle, and it is the tougher target for a thief. The THETAG's 304 body and brass core resist rust well, but its 30 mm size and thin shackle suit light duty, not a high-security gate.

  • Choose the THETAG 304 stainless padlock if you need a light, rust-resistant keyed lock with spare keys for a locker, cabinet, shed or bag.
  • Choose the Master Lock 40THC 2-pack if you are locking a gate, container or outbuilding and want two shrouded disc locks from a long-established lock brand.

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 garden gate?
The Master Lock 40THC. Its shroud covers the shackle, so a thief has almost nothing to cut, and the two-pack lets you lock a gate and a shed with the same product.
Which resists rust better?
The THETAG. Its 304 stainless body, brass core and drain holes are built for rain and coastal air. The Master Lock is stainless too, but its disc mechanism needs occasional oil to keep grit out.
Is the THETAG strong enough for a storage unit?
No. Its 30 mm body and exposed shackle suit lockers, cabinets and bags. For a storage unit or container, use the shrouded Master Lock.
Do the two Master Lock padlocks share a key?
No. Each lock in the 40THC two-pack comes with its own key, so you carry two keys unless you have them keyed alike.
Which lasts longer outdoors?
Both hold up, but for different reasons. The THETAG fights corrosion with stainless steel and drain holes. The Master Lock fights cutting with its shroud, but its disc mechanism needs periodic lubrication to stay smooth.
Is the Master Lock worth stepping up to?
Yes if the lock guards something valuable or sits where someone could attack it. For a gym locker or cabinet, the lighter THETAG is enough.
