Lang ROW-0810DHM Offset Box End Wrench 1/4 X 5/16 in 12 Pt

Product Description

The LANG ROW-0810DHM is a double-end ratcheting offset box end wrench sized 1/4 inch by 5/16 inch, designed for fastener work in confined or tight-clearance spaces. The 25-degree head offset angle allows the working face to clear obstructions that a standard flat wrench cannot. With 12-point box ends on both sides, it seats securely on hex fasteners and reduces the arc of swing needed to advance a bolt or nut. The ratcheting mechanism is reversible, so the tech does not need to reposition the wrench for the return stroke. Construction is steel with a chrome-plated finish for corrosion resistance. Weight is 0.175 pounds, keeping hand fatigue low during repetitive use.

This wrench is well-suited for HVAC, plumbing, and mechanical service work where small fasteners sit in recessed panels, behind brackets, or near tubing runs. The compact 1/4 inch and 5/16 inch sizing covers common sheet-metal screw heads, access panel hardware, and small mechanical fasteners found throughout residential and light commercial equipment. The double-end configuration means two sizes in one tool, reducing the number of tools needed at the service call.

Key Features

• Ratcheting action with reversing mechanism eliminates need to reposition on return stroke
• 25-degree head offset angle clears obstructions in tight or recessed fastener locations
• 12-point box ends seat on hex fasteners and allow a shorter swing arc
• Double-end design provides both 1/4 inch and 5/16 inch sizes in a single tool
• Chrome-plated steel construction resists corrosion and wipes clean easily
• Lightweight at 0.175 pounds, reducing fatigue during repetitive fastener work

Compatibility

Designed for use with standard 1/4 inch and 5/16 inch hex fasteners. Suitable for general mechanical, HVAC, plumbing, and electrical service applications where offset ratcheting box end wrenches are required.

Installation Notes

This tool is used by HVAC technicians, plumbers, electricians, and general service mechanics on equipment requiring small-fastener work. Always ensure the box end is fully seated on the fastener before applying torque to avoid rounding. Confirm the ratchet direction is set correctly before use in each direction. Store with other hand tools away from moisture to preserve the chrome finish.
