Open end wrench Gedore R05125012 2 kg 57 mm height

The Gedore R05125012 open end wrench is a professional-grade hand tool engineered for heavy-duty fastening and loosening tasks. Weighing approximately 2 kg with a 57 mm head height, this wrench provides a robust construction that supports high torque transfer and reliable grip on large fasteners. Manufactured by Gedore, the tool is designed for use in workshops, industrial maintenance, and mechanical repair environments where strength and durability are required.

Advantages

This open end wrench combines a solid, balanced weight with a reinforced head profile to reduce deformation under load and to maintain contact with hexagonal or squared fastener faces. Its substantial mass contributes to stability during application, improving control when applying torque. The head height facilitates access in deeper recesses and on larger bolts while maintaining clearance for hand positioning.

Suitable for

• Automotive and truck maintenance
• Industrial assembly and disassembly
• Heavy machinery repair
• Construction and infrastructure jobs involving large fasteners

Key specifications

• Tool type: open end wrench
• Approximate weight: 2 kg
• Head height: 57 mm
• Material: high-strength alloy steel (heat-treated)
• Finish: industrial protective finish to resist corrosion and wear
• Working range: suitable for large-diameter fasteners

How to use

Select the correct jaw size to match the fastener before positioning the open end of the wrench fully onto the flats of the nut or bolt. Ensure full seating to minimize slippage, then apply steady, controlled force to turn the fastener. For stubborn or seized fasteners, use gradual incremental force rather than sudden impact to avoid damaging the wrench or the fastener. Maintain a safe hand position and, when possible, use a supporting tool or assist to prevent sudden movement.

Recommendations

Inspect the wrench before each use for signs of wear, cracks, or deformation. Clean and store in a dry environment to preserve the protective finish. Use appropriate personal protective equipment and avoid using the wrench with extension bars or cheater pipes unless the tool is specifically rated for such use.
