Open-end wrench STANLEY FATMAX FMMT13077-0, stainless steel, 30x32 mm, 299 mm

STANLEY FATMAX FMMT13077-0 open-end wrench in stainless steel with a chrome finish is a single-piece hand tool sized 30x32 mm and 299 mm long. Designed for working with large nuts and bolts, the tool combines a solid stainless-steel construction with a precision-formed open jaw profile to deliver reliable torque transfer during tightening and loosening operations. The wrench weighs approximately 482 g and is supplied as a single unit suitable for workshop, automotive and maintenance toolkits.

Advantages

The stainless-steel body resists corrosion while the chrome finish facilitates cleaning and reduces surface wear. A single-piece forged construction increases strength and minimizes the risk of tool deformation under load. The two-size open-end heads provide immediate access to large fasteners without the need for socket adapters, and the 299 mm length gives additional leverage for higher torque applications.

Suitable for

• Automotive repair and servicing of large nuts and bolts
• Industrial maintenance and machinery adjustments
• Construction site assemblies and disassembly tasks
• General workshop use for heavy-duty fastening

Key specifications

• Material: stainless steel with chrome finish
• Open-end sizes: 30 mm and 32 mm
• Overall length: 299 mm
• Weight: approximately 482 g
• Single-piece forged design for increased strength

How to use

Select the appropriate open-end size for the nut or bolt and position the wrench fully over the fastener to ensure maximum surface contact. Apply steady, controlled force to turn the wrench in the required direction; for stubborn fasteners, increase leverage by using the longer arm while maintaining correct alignment to avoid rounding the fastener edges. After use, wipe the chrome finish clean to remove grease and debris and store the wrench in a dry place to maintain its corrosion resistance.

Usage recommendations

Use the wrench for manual tightening and loosening within recommended torque limits for the fastener size; avoid using the tool with impact devices or as a hammer. Inspect the wrench regularly for wear or damage and replace if jaw deformation or cracks are present.
