Set of MEGA Combination Wrenches 8 pcs 6–22 mm model 34428

MEGA 34428 is an 8-piece set of combination wrenches that covers metric sizes from 6 mm to 22 mm. Each tool combines an open-end jaw on one side and a closed ring (box) on the other, offering versatility for turning nuts and bolts in confined and exposed positions. The set is intended for general mechanical tasks and provides a compact selection of commonly used sizes for workshop benches, mobile toolkits, bicycle maintenance, plumbing fittings and household repairs.

Advantages

The wrenches are made to offer a balance of accessibility and torque: the open end allows quick engagement with fasteners while the box end provides more contact surface for higher torque and reduced rounding. The set covers a range of metric sizes that eliminates the need to search for individual wrenches during routine maintenance. The paired open and box ends increase usability across different repair scenarios and the compact assortment simplifies storage and transport.

How to use

Select the wrench size matching the fastener head, engage the box end for maximum contact when higher torque or reduced slippage is required, and use the open end for quick placement or when access is limited. Apply steady force and avoid sudden impacts to reduce risk of rounding bolt heads. For best results, position the wrench so that force is applied toward the fixed jaw to minimize stress on the fastener. Store the set in a toolbox or the supplied holder, if included, to keep sizes organized and readily accessible.

Usage recommendations

Use the box end for tightening or loosening hardened or corroded fasteners and the open end for initial alignment or in tight spaces. Inspect wrenches before use for wear or damage and pair with appropriate safety measures such as eye protection when working on pressurized systems or overhead tasks.
