Extra-Long Box End Wrench
The Capri Tools CP11800-38716 is a 3/8 in x 7/16 in wrench built for mechanics who need reach into deep recesses. Its extra-long handle provides added leverage for stubborn fasteners. The 12-point WaveDrive box end grips bolt flats to reduce rounding. Premium Chrome Molybdenum steel and MaxChrome plating deliver strength and corrosion resistance.
Installation and Common Issues
Slip the box end over the fastener; the 0-degree offset keeps the handle flat for a straight pull in tight clearance. The thin-walled profile fits recessed bolts where standard wrenches cannot reach. Applying excessive force on damaged or corroded bolts can still round the fastener despite the WaveDrive design. Large stamped sizing remains legible so you grab the correct end quickly.
Pre-Purchase Checks
Verify the fastener sizes are 3/8 in and 7/16 in before ordering. Ensure the work area allows the extra-long handle length to swing without obstruction. Confirm the 0-degree offset profile suits the accessibility of your specific bolts. Note the California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.
