Open-end Wrench Topex 41 mm single-sided (model 35D632)

The Topex open-end wrench with a 41 mm single-sided jaw is a hand tool designed for turning compatible nuts and bolts where an open jaw provides better access than a box-end or socket. The fixed-profile 41 mm opening gives a stable contact surface for torque transfer, and the single-sided design allows working in spaces where the opposite side of the fastener is accessible. The tool is intended for general maintenance, machinery servicing, plumbing and automotive repair in workshop or on-site environments.

Advantages

The wrench offers a precise 41 mm open jaw that fits standard fasteners of that size, delivering reliable mechanical leverage and reduced risk of rounding. Its solid construction ensures durability under repeated use and consistent torque transmission. The single-sided head provides easier approach angles for fasteners located against surfaces or in shallow recesses, and the straight handle allows controlled manual operation during tightening or loosening.

Suitable for

• Turning 41 mm nuts and bolts in mechanical equipment
• Automotive repair tasks requiring an open jaw
• Plumbing connections and fittings accessible from one side
• General maintenance and workshop use

Key specifications

• Jaw size: 41 mm open-end
• Head style: single-sided open jaw
• Intended use: manual turning of nuts and bolts
• Construction: one-piece solid metal design for torque transfer
• Typical applications: machinery, automotive, plumbing, maintenance

How to use

Select the wrench when the fastener size corresponds to the 41 mm open jaw. Place the open jaws squarely over the nut or bolt head so contact is made on opposing flat faces. Apply steady, controlled force to the handle in the required direction to loosen or tighten the fastener. Ensure the wrench is fully seated on the fastener before applying high torque to reduce slippage and avoid damage to the fastener or tool.

Usage recommendations

Inspect the wrench for wear or deformation before use, and avoid applying impact force with a hammer unless the tool is specifically rated for such use. Use appropriate hand protection and correct body positioning to maintain control. Store the wrench in a dry place to limit corrosion and periodically clean contact surfaces to preserve fit accuracy.
