The word 'driftpin' is formed from 'drift' (from Old English 'drift', meaning a driving or a current) and 'pin' (from Old English 'pinn', meaning a small, pointed object). The term 'driftpin' refers to a small pin used to hold or guide something in a current or drift.
Think of a 'drift' as a current that guides something, and a 'pin' as a small object that holds things in place. A driftpin is a pin that helps keep things steady in a drift.
