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.

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.

EN 12320 designates levels of security for padlocks on a scale of 1 to 6. The higher the rating, the harder it is and the longer it takes to break into or damage the padlock. Padlocks are tested against attacks such as powerful blows, cutting, drilling, pulling, and twisting.

Tested to withstand the toughest break-in methods, these padlocks keep storage containers, gates, and other outdoor equipment safe when you aren’t around. They fit around oversized hasps or large chains thanks to their extra-long shackle. They’re rated UL 437 or EN 12320 to prevent access from lockpicking, hammering, cutting, and more. An internal plate blocks drill bits from penetrating the cylinder. They’re made from materials that resist corrosion caused by rain and snow. Choose keyed differently locks if you need locks that each open with a different key.

Padlocks with a dual-locking shackle prevent attempts to break them open from prying, shimming, or tapping because both ends of the shackle lock inside the body.

Hardened-steel-body locks are stronger than brass-body and stainless steel-body locks. Locks with a chrome-plated body have added strength and an extra layer of protection against corrosion.

Chrome-plated boron carbide shackles are the hardest and most cut-resistant shackle material. They’re plated for added strength and an extra layer of protection against corrosion.

Padlocks with a keyhole cover keep out water and debris to protect the cylinder from freezing, corroding, and jamming. They have a tethered cap for an extra-tight seal.

Disc-tumbler key locking mechanisms are harder to pick than basic warded locking mechanisms.

EN 12320 designates levels of security for padlocks on a scale of 1 to 6. The higher the rating, the harder it is and the longer it takes to break into or damage the padlock.
