Hex key (allen wrench) Dedra 17F041Z, single-piece, hex size 1/2" (imperial)

Dedra 17F041Z is a single-piece hex key (Allen wrench) with an imperial hex size of 1/2". Built as a one-piece tool, it is intended for driving hexagonal fasteners in repair, assembly and maintenance tasks. The compact form factor and straightforward design make it suitable for workshop, DIY and professional environments where a robust, simple wrench for imperial fasteners is required.

Advantages

The one-piece construction provides increased strength and reduced risk of joint failure compared with multi-piece designs. A 1/2" hex tip offers secure engagement with compatible fasteners to minimise rounding and slipping during torque application. The compact length promotes access in confined spaces while keeping tool control. The straightforward design facilitates quick identification and use alongside other hand tools.

Suitable for

• Driving and removing 1/2" hex-head fasteners in maintenance and repair work
• Assembly tasks using imperial hex fasteners
• Workshop and garage use where a durable single-piece hex key is required
• DIY projects that involve furniture, equipment or machinery with imperial hex screws

Key specifications

• Tool type: single-piece hex key (Allen wrench)
• Hex size: 1/2" (imperial)
• Material: hardened steel construction for improved strength and durability
• Finish: corrosion-resistant surface treatment to extend service life
• Design: straight, L-style single-piece profile for leverage and access

How to use

Insert the 1/2" hex tip fully into the hexagonal socket of the fastener to ensure maximum contact. Apply steady turning force while maintaining perpendicular alignment to reduce the risk of stripping the fastener. Use the long arm for higher torque and the short arm for working in tighter spaces. After use, wipe the tool clean and store it in a toolbox or rack to prevent corrosion and maintain condition.

Usage recommendations

For optimal results, pair the hex key with fasteners that match the 1/2" imperial size and avoid using the tool with damaged or rounded fastener heads. When greater torque is required, consider using a longer handle or a torque-limiting approach to prevent overloading the fastener or the tool.
