Hex key (Allen key) Dedra 17F003Z — single 1/2" hex key

Dedra 17F003Z is a single 1/2" hex (Allen) key designed for driving larger imperial hex-socket fasteners. The tool features a one-piece design that delivers a solid, non-adjustable lever for applying torque in maintenance, assembly and repair tasks. Its compact form is suitable for storage in a toolbox or for occasional use in workshops and at home where a larger imperial hex key is required.

Advantages

The single-piece construction provides reliable rigidity and straightforward handling without moving parts. Its 1/2" imperial size fits corresponding hex-socket bolts and screws used in automotive, industrial and household applications. The steel construction ensures durability under regular use, while the compact, minimalist design is easy to carry and store.

Suitable for

• Driving 1/2" hex-socket bolts and screws
• Automotive maintenance and mechanical repairs
• Industrial assembly and equipment servicing
• Home repairs and furniture assembly requiring larger imperial hex keys

Key specifications

• Tool type: single hex (Allen) key
• Size: 1/2" (imperial)
• Design: one-piece L-shaped key
• Material: hardened steel (tool-grade)
• Finish: plain or corrosion-resistant coating depending on production batch

How to use

Insert the 1/2" hex end fully into the matching hex-socket fastener to ensure proper engagement. Apply steady torque using the longer arm for leverage or the shorter arm for higher torque control, depending on accessibility and required force. Maintain alignment between key and fastener to avoid rounding the fastener head. After use, wipe the tool clean and store it in a toolbox or holder to protect the working surfaces.

Usage recommendations

Use the key only with correctly sized 1/2" hex sockets to prevent damage to the tool or fastener. If extra torque is required, consider using a longer breaker bar or a properly rated torque wrench rather than applying excessive force to the hex key. Inspect the key for wear or rounding before critical tasks and replace if deformation is present.
