Meanings

To eat food very quickly, often without properly chewing it.
"He bolted down his lunch in five minutes and rushed back to his desk."
The 'fasten with bolts' sense is the primary meaning and is common in technical and DIY contexts. The eating sense (eating very quickly) is less frequent for 'bolt down' specifically — 'bolt' alone, or 'wolf down', is more natural for that meaning.
