The selection between #12 and #12 Easy Apply (40 mm) eyelets depends on the application type. The stronger #12 eyelets provide solid eyelet attachment and are suitable for heavy duty jobs such as tarpaulins, tarps or heavy curtains.

The #12 Easy Apply Eyelets, on the other hand, are made of a slightly thinner material. Due to their shorter necks, the  #12 Easy Apply Eyelets are suitable for regular use curtains and provide a more delicate look after attachment. Moreover, it needs lesser attachment force which in turn allows attachment with much a wider series of machines.
