An unbolted safe is a strongbox with a handle for carrying it away · review
A furniture safe for A5 documents with a freely programmable three-to-eight digit code, a silenceable keypad and a manual override. HMF publishes the steel thicknesses: 1 mm (0.04 in) walls and a 3 mm (0.12 in) door.
The conclusion The only safe here whose maker publishes the wall thickness as well as the door. Judge it on that number and bolt it down.
HMF publishes something almost nobody in this category does: how thick the metal is. One millimeter of wall, three of door.
It means this safe resists hands, a screwdriver and a determined teenager, and it does not resist a cordless angle grinder. That is the honest reading, and it applies to most safes at this price whether or not their makers say so.
Publishing it is to HMF’s credit, and it is the reason this page can describe the safe accurately rather than in adjectives.
Single-walled, with no insulating layer. A fire safe is two skins with fire material between them, and the documents in this one would not survive a house fire. That is a different product — there is a hub for it in this catalog — and the two should not be confused because both are steel boxes.
Small and genuinely useful. A safe that beeps on every entry announces itself through a wall, and in an apartment or a shared house that is information you would rather not broadcast.
Bolt it down. An A5 furniture safe is carried out under one arm otherwise, and everything above becomes academic.
A cupboard, a wardrobe or an office, for documents and cash rather than for anything irreplaceable.
Listed but with no offer on the American Amazon store — the reference exists there and nobody is currently selling it.

Because it lets you judge the safe honestly instead of guessing. One millimeter of wall and three of door is a deterrent against hands and a screwdriver, and it is not a barrier against a cordless grinder. In this hub, only the Kesser publishes a figure too, for its door: 4 mm (0.16 in).
Because a safe that beeps every time it is opened tells anybody nearby that there is a safe and where it is. In an apartment with thin walls, or a shared house, that is a real consideration.
It means no fire protection. Fire safes are double-walled with an insulating layer between; this is one skin of steel. Documents inside will not survive a house fire, and the fireproof boxes elsewhere in this catalog are the answer to that different problem.
