Tool set DeWalt flat-ring wrenches 12-piece KT-3312MP, metric sizes

DeWalt 12-piece flat-ring wrenches KT-3312MP provide a set of metric combination wrenches designed for general mechanical and maintenance tasks. Each wrench features a flat open-end jaw on one side and a ring end on the other, offering the flexibility to work with fasteners in confined spaces and on recessed or rounded heads. The set covers a range of commonly used metric sizes to meet workshop, automotive and assembly requirements.

Advantages

The flat open jaw allows access where a full-profile wrench cannot reach, while the ring end ensures secure engagement with bolt heads to reduce rounding. Manufactured to consistent size tolerances, the set supports reliable fit and torque transfer. Compact stacking or storage of the 12 pieces saves bench and toolbox space and simplifies selection of the correct size for the job.

Suitable for

• Automotive repair and maintenance
• General workshop and mechanical assembly
• Plumbing and HVAC service where space is limited
• Field service and mobile toolkits for technicians

Key specifications

• Tool type: combination/flat-ring wrenches (open end + ring end)
• Number of pieces: 12
• Measurement system: metric
• Material and finish: chrome-plated or corrosion-resistant steel finish suitable for workshop use
• Design: slim/flat profile for access in tight spaces
• Usage: manual tightening and loosening of nuts and bolts

How to use

Select the wrench that corresponds to the fastener size, place the open jaw or ring end onto the nut or bolt head, and apply steady hand force to turn. Use the ring end when maximum contact and torque distribution are required; use the flat open end to reach fasteners in narrow or recessed positions. Inspect the contact fit before applying force and avoid excessive impact loading that can damage the wrench or fastener.

Usage recommendations

Maintain the tools by wiping clean after use and storing them dry to prevent corrosion. For repeated high-torque applications, use the ring end whenever possible and replace any wrench that shows significant wear or deformation to ensure safe and accurate performance.
