Provided is a tension control bolt assembly for securing two or more substrates together through a blind hole. The assembly includes a bolt having a central shaft attached to a proximal head. The bolt includes one or more engagement surfaces on a proximal portion configured to be engaged by an associated application tool. The proximal portion is mechanically separable from the central shaft. The tension control bolt assembly also includes a first washer which defines structure to enable the bolt and the first washer to be inserted into a vertically oriented substrate hole. The tension control bolt assembly includes a second washer and a nut. One example includes a bolt having one or two complete revolutions of threads exposed after proper tightening of the nut. Another example includes a serrated surface configured to limit rotational motion during a fastening operation. |
