Combination wrench STANLEY FMMT13041-0, 18 mm, chromium-vanadium steel, stainless finish

STANLEY FMMT13041-0 is an 18 mm combination wrench crafted from chromium-vanadium steel with a stainless (satin chrome) finish. The tool pairs an open-end jaw and a 12-point box end to tighten and loosen fasteners, and features a 15° offset on the box end to improve access in confined spaces. Its overall dimensions are approximately 285 mm in length, 44 mm in width and 30 mm in height, making it suitable for automotive, maintenance and general mechanical tasks.

Advantages

The wrench is forged from chrome-vanadium steel and finished with a satin chrome surface to resist corrosion and provide lasting strength. The combination of an open-end and a 12-point box end increases versatility for different fastener types, while the 15° offset on the boxed end doubles the access angle and creates clearance from obstructions or hands. A non-slip profile improves grip during use, and the compact length with an integrated pocket holder supports convenient portability.

Suitable for

• Automotive repair and servicing
• General mechanical maintenance
• Assembly and disassembly of machinery and equipment
• Maintenance tasks in workshops and garages

How to use

Select the 18 mm opening to match the fastener head, position the appropriate end (open or box) on the fastener, and apply steady turning force. Use the 12-point box end for improved contact on hexagonal fasteners and the open end when quick placement or side access is needed. The 15° offset on the boxed end provides extra clearance for knuckles and obstacles; flip the wrench if additional angle is required to continue turning. Keep hands clear of pinch points and avoid using the wrench with extension bars or cheater pipes unless the tool is rated for such use.

Usage recommendations

Store the wrench in a dry place to maintain the satin chrome finish and wipe clean after use to prevent buildup. Inspect the tool before each use for deformation or wear, and replace if any cracking or rounding of the jaws is observed. Use the wrench within its intended 18 mm capacity and avoid excessive impact or overload to preserve accuracy and safety.
