How to use

Select the wrench size that matches the fastener and fit the ring end for maximum contact or the open end for quick placement. Apply steady torque while keeping the wrench aligned with the fastener axis to avoid rounding. For stubborn fasteners, use incremental force and ensure correct engagement before applying higher torque. Store wrenches in the provided organizer after use to keep sizes sorted and protect the tools from damage.

Recommendations

Use the ring end for high-torque loosening or tightening and the open end for quick adjustments in tight spaces. Inspect wrenches for wear before use, avoid excessive prying or impact on the wrench itself, and follow standard safety practices such as wearing eye protection and using appropriate leverage to prevent slippage.
