Spanner wrench Proline 46842, set of 6 pieces

Proline 46842 is a set of six spanner wrenches designed for turning and securing fasteners and fittings in confined or hard-to-reach spaces. Supplied as a compact 6-piece pack, the set covers common metric sizes and is suitable for maintenance, assembly and repair tasks where precise access and control are required. Open eyelets on the wrenches allow work around protruding studs, cables or sensors and simplify removal and installation in tight assemblies.

Advantages

The set includes six different sizes to match a wide range of nuts and bolts, reducing the need to improvise with incorrect tools. Each wrench provides a slim profile for clearance in narrow gaps and the open eyelet design enables working around obstructing components without bending or disconnecting wiring. Being organised as a small set, it is easy to store in a toolbox or to carry to job sites for on-site repairs and servicing.

Suitable for

• Maintenance and servicing of machinery and equipment
• Automotive repair and under-dash or engine-bay work
• Assembly and disassembly of fittings in tight spaces
• Electrical and sensor removal where wiring must remain intact
• General workshop and field service tasks

How to use

Select the wrench size that fits snugly over the nut or bolt head to avoid rounding. Position the open eyelet around the fastener or component, taking care to avoid contact with exposed wiring or sensors. Apply steady turning force in the required direction, using controlled movements to prevent slippage. When working in confined areas, use the slim profile to reach the fastener while keeping clearance from nearby parts; if necessary, reposition the workpiece or use additional leverage points to complete tightening or loosening.

Usage recommendations

Inspect the wrench and fastener for wear or damage before use. For electrical or sensor-related tasks, ensure power is isolated where required and avoid pulling on cables while operating the tool. Store the set in a dry toolbox to prevent corrosion and keep sizes organised to maintain quick access on the job.
