Hand wrench set Rockforce RF-5122P — 12-piece flat wrenches 6–32 mm, canvas roll

Rockforce RF-5122P is a 12-piece set of flat (open-end) wrenches covering metric sizes from 6 mm to 32 mm, supplied in a canvas roll for compact storage and easy transport. The set includes commonly used sizes suitable for general mechanical work, routine maintenance and assembly tasks. Each wrench has an open-end profile designed for accessing nuts and bolts in tight spaces where ring or socket wrenches are impractical.

Advantages

The wrenches are organized in a canvas roll that keeps each tool secure and visible, simplifying selection and preventing loss during transport. Constructed from tool-grade alloy steel with heat treatment for strength and wear resistance, the set offers consistent jaw fit across sizes and reliable torque transfer when tightening or loosening fasteners. The flat open-end design enables quick repositioning and use in constrained positions on machinery, piping and equipment.

Suitable for

• General mechanical repairs and maintenance in workshops
• On-site service and field repairs where compact tool storage is required
• Assembly work involving metric fasteners
• Plumbing, HVAC and light engineering tasks with exposed nuts and bolts
• Automotive maintenance where open-end access is needed

Key specifications

• Number of pieces: 12
• Wrench type: flat (open-end) wrenches
• Metric sizes included: 6 mm to 32 mm (range of twelve incremental sizes)
• Storage: canvas roll for organized storage and transport
• Material: tool-grade alloy steel with heat treatment (hardened and tempered)
• Finish: corrosion-resistant surface treatment for durability

How to use

Select the correct wrench size that fits the nut or bolt snugly to minimize rounding. Position the open jaws onto the fastener and apply steady force, ensuring the wrench is seated fully on the flats. For tight spaces, reposition the open-end as needed and work in small increments to avoid slipping. After use, clean any grease or debris from the wrench surfaces and return each tool to its designated pocket in the canvas roll to maintain organization and protect tool condition.

Usage recommendations

Use these flat wrenches for operations where quick access and frequent repositioning are required; avoid using open-end wrenches on rounded or damaged fasteners. For high-torque applications, consider using appropriate ring or socket tools to reduce the risk of tool or fastener damage. Store the canvas roll in a dry place to prevent corrosion and inspect tools periodically for wear.
