Hex Key (Allen Key) Dedra 17F047Z, 1/2" (1 pc)

Dedra 17F047Z is a single hex (Allen) key with a 1/2" imperial size designed for driving hexagonal socket fasteners. This compact hand tool is intended for tasks that require a 1/2" hex driver in workshop, garage or domestic environments. Its simple one-piece design provides straightforward access to recessed hex bolts and socket-head fasteners where a larger driver or multi-piece set is unnecessary.

Advantages

The 1/2" hex key offers a solid fit for compatible hex socket fasteners, enabling reliable torque transmission and reduced rounding of bolt heads. Its compact length allows access in confined spaces while remaining easy to carry in a toolbox. The single-tool format eliminates the need to search through sets for the correct size and simplifies maintenance and quick repairs. The tool is durable for typical workshop and household use when applied within its intended size and torque range.

Suitable for

• Driving and removing 1/2" hex socket bolts and screws
• Assembly and disassembly of machinery and equipment that use 1/2" hex fasteners
• Maintenance tasks in workshops, garages and home settings
• Quick repairs where a single, correct-size hex key is required

Key specifications

• Tool type: single hex (Allen) key
• Size: 1/2" (imperial)
• Material: hand tool metal construction suitable for standard use
• Format: one-piece L-shaped driver for direct hex engagement
• Intended application: driving hexagonal socket fasteners

How to use

Select the 1/2" hex key and insert the short or long arm into the hex socket of the fastener to establish a full seating. Apply steady manual force to turn the key clockwise to tighten or counterclockwise to loosen, using the longer arm for increased leverage if needed. Avoid applying excessive torque beyond the capability of the tool and the fastener; if higher torque is required, use a tool specifically rated for that purpose. After use, store the key in a dry toolbox or holder to prevent corrosion and maintain its shape.

Usage recommendations

Use the Dedra 1/2" hex key only with matching 1/2" hex sockets and bolts. Inspect fastener heads and the tool tip before use to ensure proper engagement. For stubborn or high-torque fasteners, consider a longer lever or a torque-rated tool to avoid damaging the key or the fastener.
