Hex key (Allen wrench) Dedra 17F004Z – single 1/2" imperial size

Dedra 17F004Z is a single-piece hex key (Allen wrench) in a 1/2" imperial size, designed for turning hex-head fasteners and bolts. The tool has a fixed L-shaped profile that provides two working lengths and torque options: a short arm for higher torque and a long arm for reach. Made for workshop, construction and general maintenance tasks, this 1/2" hex key is intended for applications that require a robust, simple driver for imperial fasteners.

Advantages

This single 1/2" hex key offers a compact, durable design that resists deformation under typical workshop loads. The L-shaped form gives both leverage and access to recessed fasteners, and a single-piece construction eliminates joints that can loosen or fail. Its straightforward shape makes it easy to position and apply steady torque, while the imperial sizing ensures compatibility with 1/2" hex-head bolts and set screws commonly used in older equipment and imperial-standard assemblies.

Suitable for

• Workshop repairs and general maintenance
• Construction and assembly of equipment using imperial fasteners
• DIY projects that require a 1/2" hex driver
• Accessing recessed hex-head bolts where a straight driver cannot reach

Key specifications

• Tool type: single-piece L-shaped hex key (Allen wrench)
• Size: 1/2" (imperial)
• Material: hardened steel (standard for hex keys)
• Finish: practical bare or treated metal surface for wear resistance
• Drive profile: standard hexagon for driving hex-head fasteners

How to use

Insert the short or long arm of the 1/2" hex key into the hex socket of the fastener until it seats fully to avoid rounding. Use the long arm for reach or when moderate torque is sufficient; use the short arm for higher torque by holding the short end and turning the long arm. Apply steady, controlled force and ensure the key remains aligned with the fastener axis. For very tight fasteners, back-and-forth incremental turns reduce risk of slippage and rounding.

Usage recommendations

Inspect the tool and fastener before use, keeping contact surfaces clean and free of debris. Avoid applying excessive impact or bending forces beyond normal manual torque to prevent tool damage. Store the hex key in a dry toolbox or rack to limit corrosion and maintain accurate fit to 1/2" hex fasteners.
