American Lock A31 Padlock
The American Lock A31 is a rectangular aluminum padlock designed for indoor and outdoor security applications. Its hardened steel shackle resists cutting while the chrome-plated body withstands weather exposure. This model suits facility managers and homeowners needing keyed-different access control.
Keyed Different vs Keyed Alike Systems
The padlock ships keyed different so each unit operates on a unique key, replacing keyed-alike sets where one key opens every lock. The jump is worth it when distinct access per door or locker is required without master-key overhead.
Sustained Outdoor Exposure
Chrome plating and a hardened steel shackle maintain function through rain, humidity and temperature swings. The five-pin cylinder resists picking over long periods while the aluminum body avoids rust that can seize lesser locks.

Questions about this item
What shackle diameter and height does the A31 padlock need to clear for mounting?
The hardened-steel shackle is 1/4 in diameter and 1 1/2 in tall, so the hasp or chain link must accommodate those dimensions.
How do you install the A31 padlock, and what step is often missed?
Insert the 1/4 in shackle through the hasp, snap it into the rectangular aluminum body, then turn the key to engage the 5-pin cylinder; the step often missed is verifying the shackle fully seats before locking.
What part of the A31 padlock will need replacement over time?
The 5-pin American AK5 cylinder and keys are the only wear items; the hardened-steel shackle and chrome-plated aluminum body are weather resistant and not rekeyable.
