Combo Truss Head Toggle Bolts with Wings Strong hollow wall anchors
that come with a machine bolt and a spring-wing to match. You need not to know the exact wall thickness with this anchor, it will adjust itself to almost any thickness depending on the length of the bolt. These toggle bolts have a larger diameter head that is designed to reduce the need for the use of a washer. Many fixtures and panels have pre-drilled holes that the smaller "round head" might fall through. The Combo drive allows the installer to use either a Phillips or Slotted driver.
