Morphology
The compound is directly compositional: 'hex' denotes six/hexagonal and 'nut' denotes a threaded fastener, so 'hex nut' straightforwardly means a six-sided nut. This follows regular English compounding patterns for technical objects, so a learner who knows both constituents will readily infer the correct meaning.
Etymology
Hex nut comes from the name and the shape: hex means 'six' and the nut is a small metal piece you screw onto a bolt. Because it has six flat sides a wrench can easily hold and 'turn' it, so the name reminds you it is a six-sided nut used to hold things tight.
