screw
A screw is a tiny despot that unites objects through rotation and pressure. A minute mismatch in its size can collapse an entire assembly, laying bare the illusion of planning. It appears simple, yet slip off your hand and it becomes a trust-destroying device. The more one rejoices in DIY, the more one curses its existence, fated to shed tears over replacement tasks. Properly turned, it promises sturdiness; over-tightened, it shatters parts and spirits; under-tightened, it causes total collapse—a religion of torque and temper.
