Combination wrench Jonnesway W243641 36 x 41 mm open-ended/box-end

Jonnesway W243641 36 x 41 mm combination wrench pairs a 36 mm head with a 41 mm head, each arranged as an open-ended side and a box-end side. The tool is designed for manual tightening and loosening of nuts and bolts of matching sizes and provides the versatility of two common metric sizes in a single hand tool. Constructed for workshop and field use, it is intended to deliver reliable mechanical engagement on fasteners where precise torque application and access to confined areas are required.

Advantages

This Jonnesway combination wrench offers the convenience of two sizes in one tool, reducing the need to switch between separate wrenches. The open-ended side enables quick placement on fasteners and use in tighter spaces, while the box-end side provides a more secure grip for higher torque and reduced slippage. The metal finish resists routine wear from shop and garage environments and simplifies cleaning after use. The overall design supports consistent contact with nut and bolt heads to help protect fastener corners from rounding.

Suitable for

• Automotive repair and maintenance tasks involving 36 mm and 41 mm fasteners
• Industrial and mechanical equipment assembly or disassembly
• Field service and heavy equipment maintenance where robust hand tools are required
• General workshop tasks that require metric combination wrenches

Key specifications

• Head sizes: 36 mm and 41 mm
• Combination design with one open-ended head and one box-end head
• Material: high-strength tool steel (finish for corrosion resistance)
• Intended use: manual tightening and loosening of nuts and bolts
• Hand tool length and weight: sized to provide leverage for high-torque applications (typical for large metric combination wrenches)

How to use

Select the head that matches the nut or bolt size (36 mm or 41 mm). Place the open-ended side over the fastener for quick adjustments or use the box-end side to fully engage the fastener when applying higher torque. Ensure the wrench is seated squarely on the fastener to minimize slipping and rounding of edges. Apply steady force, repositioning your grip as necessary. For stubborn or rusted fasteners, use controlled, incremental force and verify clear access to avoid sudden slips.

Usage recommendations

Inspect the wrench for signs of wear or damage before each use. Use the box-end for final tightening or loosening to reduce fastener damage, and avoid using the wrench as a hammer or pry bar. Store in a dry place and keep clean to maintain the corrosion-resistant finish and reliable fit on 36 mm and 41 mm fasteners.
