| The HD200 heavy duty underwater marine tool is engineered for easy use by divers in depths down to 150 meters. It utilizes expandable pre-loaded, waterproof barrels to drive fasteners or threaded studs into steel or concrete of high compressive strength. Barrels are pre-loaded at the surface which means the diver can take enough charges down with him to do the job, not needing to return to the surface regularly as with other systems. |

Why a fastener holds in steel
Holding power in steel depends on the elasticity of the steel. The steel pushes back on the shank of the fastener. Drop a marble into water; the water parts, the marble continues down, the water closes back. This is similar to the reaction when a fastener penetrates the steel. In steel, the point of the fastener must penetrates completely. If not, the spring action of the steel pushes back on the radiused portion of the point and tends to force the fastener out. With the point through, the amount of holding power in steel depends on the thickness of the steel and the diameter of the fastener shank.
Note - When risk of explosion special precautions is required. |
