Abstract

A gutter fastener (10) having a first shank portion (14) with a head (12a) integrally formed on one end and a second shank portion (16) integrally formed with the opposite end. The first shank portion has a length (L1) substantially equal to the water collecting opening in a gutter (20), while the second shank portion has a length (L2) substantially equal to one half the length of the first shank portion.
The second shank portion includes screw-like threads (50) for engaging the facial panel (24) behind a gutter and enabling a more secure connection between the two.
