What is the minimum steel thickness required for a lock-away safe?

• A. 1mm
• B. 2mm
• C. 3mm
• D. 4mm

Answer: (B)

Steel thickness in a lock-away safe determines how well it resists brute-force attempts. For a portable safe, you want enough strength without making it too heavy or expensive. Two millimeters is the practical minimum: thick enough to deter easy prying or cutting by casual attackers, while keeping the safe portable. One millimeter is too flimsy and can be bent or breached too easily. Pushing to three or four millimeters adds weight and cost with diminishing security gains for a portable unit. Remember, overall security also depends on the locking mechanism, door reinforcement, hinges, and how the safe is anchored, but as a baseline, two millimeters is the standard minimum.
