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 hardened steel bodies are strong and withstand physical attacks better than padlocks with steel bodies. They also provide better corrosion resistance. Designated EN12320 Grade 4, they were tested against powerful blows, cutting, drilling, pulling, and twisting. Their shackles are boron carbide, the hardest and most cut-resistant shackle material.Padlocks with tumbler discs are difficult to pick. 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.

Lock outdoor storage containers, perimeter gates, and valuable equipment with peace of mind. The chrome-plated body on these padlocks resists corrosion from rain and snow. Rated UL 437 or EN 12320, they’ve passed a test to fend off break-ins from lockpicking, hammering, cutting, and more, making them some of the most secure padlocks we offer. If someone tries drilling them, an internal plate blocks the drill bit from penetrating the cylinder. Both ends of the shackle lock inside the body to make it difficult to force them open from prying or shimming. For extra security, these padlocks are keyed differently, so the same key can’t be used with multiple locks.

Brass-body locks have excellent corrosion resistance, but they’re not as strong as steel-body locks. Hardened steel-body locks are strong, and they’re less likely to deform from break-in attempts than brass-body locks. To keep the locking mechanism from freezing, corroding, or jamming from water and debris, they come with a tethered metal cap to cover the key cylinder.

Hardened boron alloy shackles are made of the hardest and most cut-resistant shackle material. They resist corrosion better than hardened steel shackles.

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. Those with a chrome-plated hardened steel body are even stronger. They also have a free-spinning plate within the key cylinder, which spins continuously to prevent a drill bit from penetrating the cylinder. Their boron carbide shackle is tougher to cut and resists corrosion better than a hardened steel shackle.

Powerful blows and break-in attempts won’t penetrate these padlocks, keeping your most valuable equipment safe. These padlocks were designed and tested to stand up to different kinds of break-in methods. If someone tries drilling the lock, a free-spinning plate within the key cylinder spins continuously to prevent the drill from penetrating the cylinder. The shackle locks at both ends to keep it from being forced open, protecting the lock from prying and shimming. Hardened for strength, the steel body and shackle resist breaking if struck.

Choose these padlocks if you need several padlocks that open with the same key.

EN 12320 designates levels of security for padlocks on a scale of 1 to 6. Grade 5 means these padlocks were tested against powerful blows, cutting, drilling, pulling, and twisting.

For added security, locks have specially designed keys that cannot be duplicated and cannot be removed when the lock is open. Choose these locks if you need several locks that open with the same key.

Stainless steel-body lock is stronger and more corrosion resistant than brass-body locks. It has a concealed shackle to make it more difficult to cut.

Stainless steel shackles are more corrosion resistant than hardened steel shackles, but not as strong.
