They have a hexagonal head and coarse threads, which provide fantastic grip and Keeping ability. Lag screws are typically utilized having a pre-drilled pilot hole and need a wrench or socket for set up.
Superior friction in threads results in quick dress in of the screw or maybe the nut. In the case of square threads, the nut is usually made from tender content and replaced when worn out.
