7/8 in x 5/16 in Offset Box End Wrench

The Capri Tools extra-long box end wrench fits 7/8 inch and 5/16 inch fasteners. Its 0-degree offset head and thin-walled profile reach recessed bolts in tight spots. The 12-point WaveDrive design distributes torque evenly to prevent rounding. Premium Chrome Molybdenum steel construction with MaxChrome plating delivers strength and corrosion resistance.

Verify fastener sizes and workspace clearance

Confirm the 7/8 inch and 5/16 inch dimensions match your hardware before ordering. The extra-long handle requires adequate swing room to utilise the added leverage. Check that the thin-walled box end can access your specific recessed bolt locations. This product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Large stamped sizing and protective finish

Size markings are stamped large to remain legible over the tool's service life. MaxChrome plating provides a polished surface that resists rust and wear during heavy use. The 12-point WaveDrive geometry reduces fastener damage compared to standard box ends. No additional accessories or software are included with this wrench.
