Hand tool set Rockforce flat wrench set 7 pcs 8–19 mm

Rockforce flat wrench set 7 pcs 8–19 mm contains seven open-ended flat wrenches in commonly used metric sizes from 8 mm to 19 mm. The set is intended for tightening and loosening hexagonal nuts and bolts in workshops, garages and during household repairs. Each wrench has a slim, flat profile to reach fasteners in confined spaces where bulkier ring or box wrenches cannot fit, making the set suitable for automotive maintenance, machinery servicing and general mechanical tasks.

Advantages

The wrenches are forged from alloy steel and finished for corrosion resistance and durability, providing reliable torque transfer and wear resistance during repeated use. The open-ended design allows quick repositioning on the fastener without removing the tool completely, and the variety of sizes in one compact set reduces the need to search for individual wrenches. The flat profile and thin jaws improve access to tight fittings and crowded assemblies.

Suitable for

• Automotive maintenance and repairs
• Workshop and garage mechanical work
• Assembly and disassembly of machinery and equipment
• Home DIY and household repairs
• Tight spaces where ring wrenches cannot be used

Key specifications

• Number of pieces: 7
• Size range: 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 19 mm
• Wrench type: open-ended (flat) wrenches
• Material: forged alloy steel with protective finish
• Profile: slim, flat design for confined-space access

How to use

Select the wrench with the correct jaw size for the nut or bolt to avoid rounding. Place the open end onto the fastener and apply steady force in the required direction, repositioning the wrench as needed to continue turning in confined spaces. Use appropriate personal protective equipment and ensure the workpiece is stable before applying torque. For stubborn or rusted fasteners, apply penetrating lubricant and allow time to work before attempting to loosen.

Usage recommendations

Match the wrench size precisely to the fastener to prevent damage; do not use the flat wrenches as hammers or pry bars. For high-torque applications, consider using a box-end or torque-rated tool. Store the set in a dry place to maintain the protective finish and inspect wrenches regularly for wear or deformation.
