Abstract
For a spring tool for actuating explosive fasteners to operate at its maximum potential the firing pin guide should be pushed securely against the rear of the fastener and the tip of the fastener should be pushed securely against the substrate. To achieve this, the action of the operator pushing the tool forward to actuate the tool moves the trigger body forward while compressing the firing spring until the trigger body travels the exact distance needed to release the trigger ball. A step or backstop insert is added to the inside of the trigger body such that at the exact distance where the trigger ball is released, the step contacts the rear of the firing pin guide so that all internal components of the tool to form a solid (contacting) stack, from the tip of the fastener to the end cap of the tool.
