Hex key (Allen wrench) Dedra 17F049Z — 1 pc, 1/2" imperial size

Dedra 17F049Z is a single hex key (Allen wrench) supplied as one piece in a 1/2" imperial size. The tool is designed for turning hexagonal socket fasteners and provides the larger diameter and leverage required for heavy-duty tightening and loosening in workshops, maintenance and assembly environments. Its compact, single-piece form makes it convenient to store and use where a strong, straight hex driver is needed.

Advantages

The Dedra 1/2" hex key offers a robust, simple design that delivers reliable torque transfer to hex socket fasteners. Because it is a single-piece tool without moving parts, it resists loosening, bending and corrosion when used within recommended load limits. The imperial sizing ensures compatibility with hardware specified in inches, reducing slippage and rounding on larger fasteners compared with undersized drivers.

Suitable for

• Workshop and mechanical repairs requiring a large hex driver
• Maintenance of industrial equipment and machinery
• Assembly and disassembly of furniture or fixtures with imperial fasteners
• Automotive or agricultural applications that use inch-based hex bolts

Key specifications

• Tool type: single-piece hex key (Allen wrench)
• Size: 1/2" (imperial)
• Quantity: 1 piece
• Drive style: straight hex key for internal hex sockets

How to use

Select the 1/2" hex key when the fastener head matches the tool size. Insert the short or long end of the key fully into the hex socket to ensure full contact between tool and fastener. Apply steady, controlled torque; for higher torque needs use the longer arm for increased leverage. Avoid using excessive force that could cause tool deformation or fastener rounding. Store the hex key in a dry place to reduce risk of corrosion.

Usage recommendations

For optimal performance, inspect the hex socket and tool tip for wear before use, match imperial-size fasteners to the 1/2" key, and apply torque evenly. Use appropriate protective equipment and consider a torque wrench for critical torque-limited applications.
