Abstract
Abstract An adjustable long bolt for connecting modular concrete form panels. The bolt is generally flat along its length and has a pair of elongated slots disposed in adjacency to opposite ends of the bolt. At least one circular hole is disposed between the slots having its mid-point disposed along a longitudinal line in longitudinal alignment with longitudinal axes of said elongated slots. The longitudinal spacing between the elongated slots with respect to the at least one circular hole being varied to enable the bolt to be installed in a larger number of adjustable positions by turning the bolt on its end through an arc of rotation of 180°.
