McMaster 11345A25 Weather- and Cut-Resistant Padlock, Laminated Steel Body, 7/16" Shackle Diameter, Master Lock Pro 6327

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 lock.
