Master Lock 6001NLFUS Padlock

The Master Lock 6001NLFUS is a rectangular steel padlock with a laminated gold body and a standard steel shackle. It uses a five-pin cylinder with a Master K17 keyway and is supplied keyed different for individual access control. The mechanical push-button design requires no electronic components or batteries. It suits anyone needing a straightforward, high-security mechanical lock for indoor or sheltered outdoor use.

Build integration and clearance

The lock body measures 2 13/32 in high by 1 3/4 in wide by 7/8 in thick, while the shackle diameter is 5/16 in with a 1 3/16 in clearance height. These dimensions determine whether the shackle fits through your hasp, chain link or gate latch. The laminated steel body resists physical attack, and the standard shackle leaves enough room for typical hardware without needing specialised fittings. No weather-resistant coating is applied, so exposure to rain or salt spray should be avoided.

Who this suits and who should look elsewhere

This padlock fits users who want a keyed-different, rekeyable-no lock with a fixed five-pin cylinder and no interchangeable core. It is not for buyers who need a weather-resistant finish, a keyed-alike or master-keyed system, or a lock that accepts an interchangeable core for future rekeying. Builders requiring a shrouded or long-shackle variant should look at other models.
