Metal Screw Interlock Riddle
Looks like everyday hardware. Solves like a hidden lock path.
Shop →If you searched “hexanut”, “lock puzzle”, or even “puzzle rubik’s puzzle”: you’re in the right place. This page focuses on tactile, satisfying mechanical challenges—locks that don’t protect your wallet, they steal your attention (in a good way).
Tip: If you love the “pattern memory” of a Rubik’s cube, jump to the cube section below. If you love “one clean click” moments, start with the lock puzzles.
A hex‑nut style take‑apart riddle: it looks like ordinary hardware (screw + nut), but hides a surprising internal lock‑path. Simple look, sneaky solve.
Lock puzzles are path‑finding + patience. Rubik’s‑style puzzles are patterns + algorithms. Different vibe, same obsession.
All picks below are desk‑friendly: easy to wrap, fun to fidget, and awkwardly hard to put down.
Best if you want that “one more try” loop—like a tiny escape mechanism in your hands.
Looks like a screw and nut. Solves like a magic trick. Great for pranks and desk flexes.
If you love cube puzzles, go for geometric builds that scratch that same “algorithm itch.”

“Hexanut” puzzles often disguise the mechanism as everyday hardware. A “lock puzzle” is any mechanical puzzle that behaves like a lock—pathfinding, alignment, and controlled movement.
Keep it fun. Most “I’m stuck!” moments are one of these.

A “hexanut” is commonly shorthand for a hex‑nut style mechanical riddle: it looks like a normal screw + nut, but the “lock” is hidden in the way the parts interact. It’s a great desk puzzle because it looks harmless—until it isn’t.
Not exactly. Rubik’s‑style puzzles are usually “combination puzzles” where you use repeatable moves to reach a solved state. Lock puzzles are closer to “pathfinding”: discover the route that frees the piece.
If you want a quick win: start with a smaller lock puzzle (Alloy S, Double G). If you want a stubborn challenge: go maze (ABC Maze, Dual‑Sided Maze) or multi‑step (Three Brothers).
Yes—especially for people who like hands‑on desk toys, escape rooms, or “I need something to do with my hands” moments. If you’re unsure, pick a conversation shape (Grenade, Heart, Koi) and you’re safe.
