DEDRA 17F042Z hex key 1 pc(s)

DEDRA 17F042Z hex key is a single-piece, L-shaped tool designed for driving hexagonal fasteners. This model provides a straight, robust shaft with a 1/2" imperial hex tip, suitable for applications where a larger hex key is required. The compact, one-piece design allows access in confined spaces while delivering the torque needed for assembly, maintenance, and repair tasks.

Advantages

The hex key is made to provide a precise fit in hex socket heads, reducing the risk of rounding fastener corners. Its single-piece construction ensures stability under load and minimizes flex during use. The 1/2" size offers high torque capacity for stubborn or high-load fasteners. Its L-shape gives both leverage and reach, enabling controlled turning and access to recessed bolts.

Suitable for

• Assembling and disassembling furniture, machinery, and equipment that use 1/2" hex fasteners
• Maintenance and repair tasks on bicycles, automotive components, and industrial installations requiring a larger hex key
• Work in workshops, garages, construction sites, and home toolkits where durable hand tools are needed

Key specifications

• Tool type: L-shaped hex key (Allen key)
• Quantity: 1 piece
• Hex size (imperial): 1/2"
• Material: high-strength steel (manufacturing-grade for hand tools)
• Finish: plain or corrosion-resistant treatment typical for hand tools

How to use

Select the 1/2" hex end and insert it fully into the hex socket of the fastener to ensure full contact. Use the short arm for high torque by holding the long arm, or use the long arm for extended reach and better access. Apply steady, controlled force to avoid slipping or rounding the fastener. For stuck fasteners, apply penetrating lubricant and allow it to work before attempting to turn. Store the hex key in a tool rack or holder to protect edges and maintain the correct shape.

Usage recommendations

Use appropriate personal protective equipment such as gloves and eye protection when working with hand tools. Do not apply impact force or use the hex key with a cheater bar or extension beyond recommended torque limits. Inspect the key for wear before use and replace if the tip becomes rounded.
