Your powder-actuated tool is not setting fasteners — either the tool is damaged or the pin and drive tool combination is wrong for the application. This #HD222 hammer drive tool is the matched component for the HD222 pin system, designed to take the full force of the powder charge and direct it correctly into the fastener. Specifically engineered for the HD222 system. The tool must handle repeated high-impact loads without deformation — using the wrong drive tool risks misfires, kickback, and fastener failure. This is the OEM component for the system. What concrete contractors and steel fabricators from Sioux City to Norfolk keep in their tool kits — the system component that makes the difference between a set fastener and a callback.
