What is the purpose of valve locks/keepers?

Valve locks, also known as keepers, are small components that fit into grooves on the valve stem. They work with the valve spring retainer to hold the valve spring assembly together, maintaining proper valve spring tension.

What does the .3110 dimension refer to?

The .3110 dimension refers to the diameter of the valve lock itself. This measurement is important for ensuring it properly mates with the valve spring retainer and the groove on the valve stem.

Are these valve locks sold individually or as a set?

These valve locks are sold as a set of 16, which is typically enough for a complete engine with 16 valves.
