Cut-Resistant Padlocks
Difficult to cut and pry open, the shackles on these padlocks are protected by shoulders. Choose these padlocks if you need locks that each open with a different key. They have random key numbers.
Padlocks with chrome-plated steel bodies have added strength and an extra layer of protection against corrosion.Padlocks with tumbler pins are more difficult to pick than those with tumbler discs. Padlocks with bump-resistant cylinders are the most tamper resistant—they have a tapered top pin that stays put to prevent unlocking when a tool is tapped into the lock.

Cut-Resistant Keyed Alike Padlocks
Raised shoulders cover most of the shackle on these padlocks, making it difficult to access and cut. More secure than standard padlocks, these are often used on unmanned access gates and other areas where added security is needed. Choose them if you need several locks that open with the same key. If the lock or key with the key number you want isn’t listed, order the "Other Key Numbers" and specify your desired key number.
Style B padlocks have a steel body, so they’re stronger and withstand physical attacks better than locks with a brass body. All are chrome plated for extra strength and corrosion resistance.
Locks with a pin-tumbler key locking mechanism are harder to pick than locks with a disc-tumbler key locking mechanism. The more pins a lock has, the harder it is to pick. Those with a bump-resistant cylinder are the most tamper resistant—they have a tapered top pin that stays put to prevent unlocking when a tool is tapped into the lock.
