Open-end wrench Kuźnia Sułkowice 46 x 50 mm (model 1-131-75-101)

Open-end wrench Kuźnia Sułkowice 46 x 50 mm (model 1-131-75-101) is a hand tool with two fixed open jaws measuring 46 mm and 50 mm. It is designed to apply direct torque to hexagonal nuts and bolts of these metric sizes and is intended for mechanical, maintenance and repair tasks in workshops, garages and industrial settings where fixed-size open-end spanners are required.

Advantages

The open-end design provides quick engagement with fasteners without the need to reposition the tool around the workpiece. Two different jaw sizes on a single wrench reduce the number of tools needed and increase efficiency when working with 46 mm and 50 mm hex fasteners. The solid forged construction ensures rigidity under load and consistent jaw alignment, enabling reliable torque transfer to nuts and bolts. A straight profile facilitates access in many common working positions and allows stable hand placement during use.

Suitable for

• Automotive repair and heavy vehicle maintenance
• Industrial assembly and machinery maintenance
• Workshop and garage mechanical tasks
• Field service where fixed metric open-end sizes are required

Key specifications

• Jaw sizes: 46 mm and 50 mm
• Type: open-end wrench with two fixed jaws
• Material: forged steel construction for strength and durability
• Finish: protective coating to resist corrosion and wear
• Profile: straight handle for direct torque application

How to use

Select the jaw size that matches the hex nut or bolt head (46 mm or 50 mm). Position the open jaw fully around the fastener so both contact faces engage the flats of the hex. Apply steady, controlled force in the required direction to loosen or tighten the fastener, keeping your hand clear of pinch points. Avoid using excessive impact or leverage beyond the tool’s intended capacity and do not use the wrench with cheater bars or extension pipes to prevent damage to the tool or fastener.

Usage recommendations

Inspect the wrench before use for visible wear, cracks or deformation of the jaws. Use the correct jaw size to minimise rounding of fastener edges. Store the wrench in a dry place and clean off oil or debris after use to maintain performance and longevity.
