Dedra 1/2" Spline Socket Bit M12, 100mm

Dedra 17F074Z — 1/2" (1 pc) is a single-piece hex (Allen) key designed for driving bolts and screws with a 1/2" hex drive. The tool provides a precise fit for compatible fasteners and is suitable for mechanical work, assembly and repair tasks where a robust imperial-sized hex key is required. Its compact, single-key format makes it convenient for toolbox storage and targeted tightening or loosening operations.

Advantages

The single-piece design offers rigidity and direct torque transfer, reducing play between key and fastener. Its 1/2" size matches standard imperial hex fasteners, ensuring a secure engagement and minimizing rounding of bolt heads. The compact form is easy to handle in confined spaces and allows for controlled application of force during assembly or maintenance.

Suitable for

• Mechanical assembly and disassembly of equipment using 1/2" hex fasteners
• Repair and maintenance tasks on machinery and vehicles with imperial-sized hex bolts
• Workshop and field service work where a single, durable 1/2" hex key is needed

Key specifications

• Tool type: single-piece hex (Allen) key
• Size: 1/2" (imperial)
• Quantity: 1 piece
• Primary use: driving hex-head bolts and screws
• Form factor: L-shaped single key for hand operation

How to use

Insert the short or long end of the hex key into the corresponding 1/2" hex socket of the bolt or screw so that the flats seat fully. Apply steady, controlled torque in the required direction to tighten or loosen the fastener. Use the longer arm for increased leverage when loosening tight bolts, and the shorter arm for greater control in confined spaces. Inspect the tool and fastener engagement before applying high torque to avoid slippage or damage.

Usage recommendations

Use the hex key with properly sized fasteners only, avoid excessive force beyond manual torque limits, and store in a dry place to prevent surface corrosion. For repetitive or high-torque applications, consider using torque-limiting tools or professional equipment to protect fasteners and the key.
