Hex Key (Allen Wrench) Dedra 17F071Z — 1/2" Imperial, 1 pc

Dedra 17F071Z is a single imperial hex key (Allen wrench) in a 1/2" size, supplied as one piece. It is intended for driving hexagonal socket screws and bolts with a 1/2" internal hex. The tool is suitable for workshop, repair and assembly tasks where a reliable, compact hex key is required for fastening, maintenance and general DIY operations.

Advantages

The 1/2" Dedra hex key offers a simple, compact design that provides direct torque transfer to hex socket fasteners. Supplied as a single sturdy piece, it eliminates the need to select from multi-key sets for occasional use. Its imperial sizing matches equipment and fasteners specified in fractional inch standards, making it practical for work on older or imported machinery and fittings. The single-piece construction reduces play and potential joint wear compared with folding or multi-link tools.

Suitable for

• Driving and removing 1/2" hex-socket bolts and screws
• Workshop maintenance and mechanical repairs
• Assembly tasks where a single imperial hex key is required
• DIY projects and home repairs involving imperial fasteners

Key specifications

• Type: Straight hex key (Allen wrench)
• Size: 1/2" (imperial)
• Quantity: 1 piece
• Intended use: Driving hexagonal socket fasteners
• Form factor: Single fixed-length tool for direct torque application

How to use

Insert the 1/2" end of the hex key fully into the hex socket of the screw or bolt to ensure maximum contact and minimize rounding. Apply steady turning force in the required direction—clockwise to tighten, counterclockwise to loosen—keeping the key aligned with the fastener axis. For higher torque needs, position the key with the long arm for greater leverage or the short arm for tighter clearances. Inspect the tool and fastener engagement before applying significant force to prevent damage to the socket or key.

Usage recommendations

Use the Dedra 1/2" hex key on correctly sized 1/2" hex sockets only and avoid excessive force that may strip the fastener. Store the tool in a dry place to prevent corrosion and check the key for wear before critical tasks. For repeated high-torque applications, consider using a longer or stronger torque-rated wrench designed for heavy-duty use.
