The wrench adjusts to fit a working range of 3\/4 inch through 2 inches, covering a wide spread of fastener sizes without swapping tools. At 6-3\/8 inches overall length, it provides a controlled grip and modest leverage suitable for precision mechanical work. The 1\/8-inch hook height seats cleanly into shallow slots, and the 11\/32-inch hook thickness adds durability under torque. This tool is used by machinists, millwrights, pump technicians, and field service mechanics.\u003c\/p\u003e\n\u003cp\u003eThe MARTIN TOOLS 471 is a general-purpose spanner wrench suited for maintenance and repair work on rotating machinery, pumps, motors, and assemblies that use slotted or notched locking hardware. Its adjustable design makes it practical for shops and service vans where carrying multiple fixed-size spanners is not feasible. The compact overall length of 6-3\/8 inches allows use in moderately confined spaces where a full-size wrench would not fit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable capacity from 3\/4 inch to 2 inches covers a broad range of slotted fasteners\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hook height seats securely in standard shallow slots and notches\u003c\/li\u003e\n  \u003cli\u003e11\/32-inch hook thickness provides resistance to deflection under load\u003c\/li\u003e\n  \u003cli\u003e6-3\/8-inch overall length offers controlled leverage for precision applications\u003c\/li\u003e\n  \u003cli\u003eSingle-tool coverage reduces the need for multiple fixed spanner sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose adjustable hook spanner wrench for use on slotted or notched fasteners with an outside diameter between 3\/4 inch and 2 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is typically used by machinists, pump technicians, and maintenance mechanics.
