All the bolts have a 3/8″ thread. The head is Tri-Groove and requires a special socket (SKU: 140011) in order to install and remove the bolt. The head design makes it difficult to grab with pliers. When used with the proper socket, considerable torque can be applied to secure the bolt.
Attention: We only sell the socket (SKU: 140011) to Property Managers and Building Managers that have an account with us. Please call to order if you are on our list. Unfortunately we will not sell the security socket to any other clients for security reasons.
