The partially concealed shackle on these padlocks means more security for your outdoor equipment and gates than a traditional padlock. Since most of the shackle is covered, it's difficult to access and cut. For durability outdoors, they’re made from materials that resist corrosion from rain and snow.

These padlocks have a pin-tumbler key locking mechanism, which is the most difficult locking mechanism to pick. The more pins the lock has, the harder it is to force open. Choose these padlocks if you need locks that each open with a different key. All have random key numbers.

Style C padlocks have a dual-locking shackle, so they prevent attempts to force them open from prying, shimming, or tapping because both ends of the shackle lock inside the body.

Steel-body locks are stronger and hold up better against break-in attempts than brass-body locks. They are also covered in plastic to prevent them from scuffing or denting nearby surfaces.

Hardened boron alloy shackles are the hardest and most cut-resistant shackle material. They also hold up against corrosion better than hardened steel shackles.

Padlocks with a keyhole cover keep out water and debris to protect the cylinder from freezing, corroding, and jamming.

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.

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.

Useful for lockout identification practices, these padlocks come in a variety of colors to catch your eye. Assign a color to individual people or departments, such as blue for plumbing or red for electrical. Use them with cables and other lockout devices to keep equipment off during maintenance or repairs. This helps you comply with OSHA 29 CFR 1910.147 procedures. All have a pin-tumbler key locking mechanism, which is the most difficult locking mechanism to pick. The more pins a lock has, the harder it is to pick.

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.

Style A locks have an aluminum body that resists corrosion better than locks with a steel body, but they’re not as strong. Their shackle is either aluminum or boron alloy, both of which resist corrosion better than a hardened steel shackle. Locks with a boron alloy shackle have the hardest and most cut-resistant shackle material.

No more lost keys or forgotten combinations—these padlocks open with your Bluetooth-enabled smartphone. Each padlock has a code for registering the lock with a free app to control it via Bluetooth. In addition to locking and unlocking the padlock, you can permanently or temporarily share access to the padlock with others, monitor when and who had access to the padlock, and receive tamper alerts. Padlocks are battery operated. If your phone is not available, you can also open the padlock using a combination on the padlock keypad.
