Ratchet wrench STANLEY FMMT13085-0, chromium-vanadium steel, 12 mm, 1 head

STANLEY FMMT13085-0 ratchet wrench is a 12 mm reversible ratcheting combination wrench forged from chromium-vanadium steel and finished with satin chrome for corrosion resistance. The tool integrates a 12-point box end with a matching open end designed to deliver reliable torque for tightening and loosening 12 mm fasteners in mechanical, automotive and maintenance work. The compact single-head design and anti-slip profile provide improved grip and control for workshop and on-site tasks.

Advantages

The wrench combines a 12-point box end and a 15° angled open end to increase access in confined spaces and reduce interference with surrounding components. A 72-tooth ratchet mechanism requires only a 5° swing arc to engage the next tooth, enabling efficient operation where movement is limited. Satin chrome plating enhances corrosion resistance while chromium-vanadium construction offers strength and wear resistance for repeated use. An integrated pocket holder improves portability for mobile technicians.

Suitable for

• Automotive repair and maintenance on 12 mm nuts and bolts
• Mechanical assembly and disassembly tasks
• Workshop use for general fastening and loosening
• On-site service and field maintenance where access is restricted

Key specifications

• Size: 12 mm metric box/open combination
• Material: chromium-vanadium steel
• Finish: satin chrome for corrosion resistance
• Ratchet teeth: 72-tooth mechanism (5° swing)
• Open end angle: 15°; box end offset: 15°
• Single reversible ratchet head with anti-slip profile
• Portable with integrated pocket holder

How to use

Select the wrench and engage the 12 mm box or open end onto the fastener. For confined spaces, use the 15° angled open end or the offset box end to improve access. Operate the ratchet by moving the handle through small arcs; the 72-tooth gear allows engagement with approximately 5° of swing. Reverse the ratchet direction as needed to tighten or loosen fasteners. After use, wipe the tool clean and store it in a toolbox or use the pocket holder for transport.

Usage recommendations

Use the appropriate end (box for higher torque and protection of fastener corners, open for quick placement) and avoid applying excessive impact loads. Regularly inspect the satin chrome finish and ratchet teeth for wear; apply light lubrication to the ratchet mechanism if movement becomes stiff. Keep the wrench clean and dry to preserve corrosion resistance and service life.
