Notched Bendable Bolts

  1. Bolt notches can be a machined (milled) or heat pressed type notch.

  2. Notched bendable bolts can be configured as either a non-tensioned headed rebar, torque-tension, Super-Twist, or INSTal bolt.

  3. All installation instructions for those type bolts are to be followed.

  4. However, when bending a notched bolt, the restraining or gripping point must not be in the notched portion of the bolt. The restraining or gripping point must be outside the notched area either towards the top or bottom of the bolt. Gripping in the notch can result in bolt failure during the bending process. DO NOT RESTRAIN IN THE NOTCHED AREA.

  5. Excessive bolt bending can cause the formation of cracks in the notched area resulting in a significant loss of bolt strength. The bolts should not be bent more than 60 degrees, and never more than 90 degrees.

  6. Once bent, and the top end of bolt is placed in the drill hole, the bolt is straightened out. Again, during the bolt straightening process, the bolt restraining or gripping point must be outside the notched area. DO NOT RESTRAIN IN THE NOTCHED AREA.

  7. Once the bolt is straightened, the installation should completed per the Installation Instructions for the particular type of bolt.
