Place Bolts — otherwise known as Locking Head Bolts, GM Lock Bolts, or Type AA Lock Bolts — are specially designed to provide a locking action between the bolt and the material being clamped. The locking comes from the crevice under the head and the slots in the top causing the head to flex as it’s tightened. These bolts are well known for their use in transition and diesel engines and many other capacities.
