Hex key (Allen wrench) Dedra 17F046Z — 1/2" imperial, single piece

Dedra 17F046Z is a single-piece hex key (Allen wrench) sized 1/2" imperial, intended for turning hex-head fasteners specified in inches. The tool offers a fixed-size driving interface with a straight, robust profile and compact form factor. It is made to provide a secure fit for large imperial hex bolts and screws used in assembly, maintenance and repair operations where a single, durable hex key is required.

Advantages

This single-piece hex key delivers a stable, non-adjustable driving surface that reduces slippage when engaging hex fasteners. Its imperial 1/2" dimension matches large inch-based hardware, enabling direct fit without adapters. The simple, solid construction minimises flex and wear under torque compared with multifunctional or folding tools. Its compact size makes it easy to store and position in confined spaces.

Suitable for

• Turning 1/2" imperial hex-head bolts and screws
• Mechanical assembly of equipment and frames using inch fasteners
• Maintenance and repair tasks in workshops and garages
• Situations requiring a single, strong hex key for repeated use

Key specifications

• Tool type: single-piece hex key (Allen wrench)
• Drive size: 1/2" (imperial)
• Material: steel construction suitable for hand torque applications
• Finish: machined surface for accurate hex engagement
• Form factor: straight, fixed-size key for one-handed operation in accessible spaces

How to use

Insert the 1/2" hex end fully into the hex recess of the fastener to ensure maximum contact area. Apply steady turning force in the required direction, using the length of the key for leverage while keeping the tool aligned with the fastener axis to avoid rounding. For high torque requirements, position the key so that body contact and hand placement reduce the risk of slippage. After use, wipe the tool and store it in a dry location to prevent corrosion.

Usage recommendations

Use the Dedra 1/2" hex key only with compatible inch-sized hex fasteners. Do not use the tool with impact drivers or apply excessive torque beyond hand-tool limits. Wear appropriate hand protection when working in greasy or confined conditions and periodically inspect the hex faces for rounding or wear.
