The Humble Allen Key
Every flat-pack box includes a folded Allen key (hex key). It's the cheapest tool that can tighten a bolt — and that's exactly why manufacturers include it.
Why Furniture Makers Love the Hex
Hex bolts resist stripping far better than Phillips screws under hand torque, and a single Allen key works for an entire piece. It also means the maker doesn't have to assume you own a screwdriver set.
The Right Way to Use It
Insert the short end into the bolt for speed, then switch to the long end for the final tighten — you'll get more leverage and a firmer joint. Keep the key at 90 degrees to the bolt; angling it rounds off the hex socket.
When the Allen Key Isn't Enough
Cam locks need the Allen key only for the bolt; the cam itself turns with a flathead or coin. If you feel resistance, stop — you're cross-threading.
Pros Bring Real Tools
A pro arrives with a full hex set, a power driver with clutch, rubber mallet, and clamps. That's why a two-hour DIY build becomes a 30-minute professional job.
