Choose these locks 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.

Zinc-body locks are more corrosion resistant than steel-body locks. However, they’re not as strong as steel-body or aluminum-body locks.

Hardened steel shackles are tougher to cut or pry than steel shackles. Those that are chrome-plated won't corrode. Disc-tumbler key locking mechanisms are harder to pick than warded locking mechanisms. Pin-tumbler key locking mechanisms are the most difficult to pick. The more pins a lock has, the harder it is to pick.

Shoulders cover most of the shackle, making it difficult to access and cut. The shackle is hardened steel, so the exposed part resists cuts better than plain steel. To prevent attempts to force them open from prying, shimming, or tapping, they are dual dead locking, so both ends of the shackle lock inside the padlock body. Because these locks are more secure than standard padlocks, they’re often used for unattended gates or storage for valuable equipment. They unlock with a five-digit combination, which means they have ten times more combinations than four-digit locks for added security. Set or reset your combination at any time.

Zinc-body locks resist corrosion better than hardened-steel-body locks but aren't as strong. They have an epoxy coating as an extra layer of corrosion protection. It also protects against scuffing nearby surfaces.

Hardened steel shackles are the least corrosion resistant but are stronger than stainless steel shackles. Chrome-plated hardened steel shackles have added strength and an extra layer of protection against corrosion.
