## Summary description

Hand tool: 21 mm open-ring (combination) wrench by King Tony, model FT-75521. Designed for tightening and loosening nuts and bolts with a 21 mm head, it combines an open-end and a ring end in one durable tool. Suitable for automotive, maintenance and assembly tasks where a precise 21 mm fit is required.

## Long description

King Tony Wrench (open-ring) 21 mm FT-75521 is a combination hand tool designed for tightening and loosening fasteners with a 21 mm head. The tool integrates an open-end jaw and a ring (box) end on a single shaft to provide access in confined areas and secure engagement for torque transfer. Manufactured from durable alloy steel with a finished surface, this 21 mm wrench suits tasks in automotive repair, general maintenance, and assembly where a precise fit and dependable grip are needed.
Advantages
The combination of an open-end and a ring end offers versatility: the open jaw allows quick placement on a fastener and work in tight spots, while the ring end provides full contact with the 21 mm head for reduced rounding and improved torque application. Solid construction and heat-treated alloy steel increase durability and resistance to wear. A calibrated profile on the ring end enhances grip on hexagonal fasteners, and a polished or coated finish improves corrosion resistance and makes the tool easier to clean.
Suitable for
 Automotive repairs and maintenance that require a 21 mm wrench
 Mechanical assembly and disassembly of machinery and equipment
 Home and workshop maintenance where both quick access and secure fastening are needed
 Field service work where a single versatile wrench reduces the number of tools carried
Key specifications
 Size: 21 mm across flats
 Type: combination wrench (open-end and ring/box end)
 Material: heat-treated alloy steel (hardened for strength)
 Finish: polished or corrosion-resistant coating
 Profile: 6-point (hex) engagement on ring end for improved contact
 Length: typical hand wrench length suitable for both access and leverage (varies by model)
How to use
Select the 21 mm end and position the open jaw over the nut or place the ring end fully onto the fastener head. For quick adjustments or where space is limited, use the open-end side and apply steady pressure while maintaining correct alignment to avoid slippage. For higher torque and a more secure hold, engage the ring end and turn using controlled force. Inspect the wrench before use for signs of wear or damage and ensure the fastener is free of debris to preserve the tool and the fastener surfaces.
Usage recommendations
Use the open-ring 21 mm wrench with steady, controlled force and avoid sudden impact loads. Do not use the wrench as a hammer or pry bar. Keep the tool clean and store it in a dry place to extend service life. When greater torque is required, use an appropriately sized torque wrench or follow manufacturer torque specifications for the fastener.
