Flat Combination Wrench Dedra 16 x 17 mm 1477

Flat Combination Wrench Dedra 16 x 17 mm is a single-piece hand tool with two fixed jaw sizes—16 mm and 17 mm—designed for manual tightening and loosening of nuts and bolts. Its compact, flat profile allows access in confined spaces and routine fastening operations in mechanical maintenance, automotive repairs and household tasks. The tool is made for direct hand use and fits standard metric fasteners of the specified sizes.

Advantages

The flat combination wrench combines an open-end and a boxed end in one compact tool, providing quick access to fasteners and secure grip where torque control is needed. Its single-piece construction reduces the risk of joint failure and improves durability during repeated use. The low-profile, slim body enables operations in tight clearances while keeping the tool lightweight and easy to handle.

Suitable for

• Automotive repair and maintenance tasks involving 16 mm and 17 mm metric fasteners
• Mechanical assembly and disassembly in workshops
• Household repairs and furniture assembly where compact tools are required
• Field service and on-site maintenance requiring a portable hand tool

Key specifications

• Tool type: flat combination wrench with open and boxed ends
• Sizes: 16 mm and 17 mm working ends
• Construction: single-piece metal body for increased strength
• Profile: slim, low-profile design for access in confined spaces
• Intended drive: manual hand operation

How to use

Select the end that matches the fastener size (16 mm or 17 mm) and position the wrench over the nut or bolt head. For the open end, engage the jaw fully and apply steady force, avoiding sudden impacts. For the boxed end, ensure full seating around the fastener to reduce rounding. Use controlled torque and, when working in tight spaces, position the wrench so the slim profile can access the fastener without obstruction.

Usage recommendations

Use the wrench only on the specified metric sizes to prevent rounding or damage. Inspect the tool before use for signs of wear or deformation. Avoid using the wrench with extensions or cheater bars that exceed recommended manual torque, and store it in a dry place to prevent corrosion.
