A shear pin can here hold a striker pin in place, preventing the striker pin from striking an initiator (primer) unless the correct force is applied.

Fig. 1. A shear formed product: a hollow cone with a thin wall thickness. Shear forming, also referred as shear spinning, is similar to metal spinning.

In a master-keyed lock, some or all of the pin chambers in the lock have three pins in them instead of two. Between the driver pin and the key pin is a third pin called the spacer pin, also known as a master wafer. Thus each pin line has two shear points, one where the driver and spacer pins meet, and one where the spacer and key pins meet. So ...
