If you put two gage blocks together perpendicular to each other, exert a small pressure, and twist the blocks to align them, the air between the blocks gets squeezed out, and the molecules in each block attract, sticking them together.

Gauge blocks stick together due to the molecular attraction known as Van der Waals forces. These forces are caused by the fluctuating electric fields of the atoms, which can create an adhesive effect between two surfaces in close contact. The flat and smooth surfaces of gauge blocks allow for a large area of contact, increasing the strength of these forces and causing the blocks to stick together.
