Set of 2 Dedra tools: 4 mm hex key (imbus) and window adjustment wrench, model 06F400

Set of 2 Dedra tools: 4 mm hex key (imbus) and window adjustment wrench, model 06F400 is a compact duo designed for mechanical fastening and precise adjustment of window hardware and furniture fittings. The set combines a standard 4 mm hex key with a dedicated window adjustment wrench to cover common tasks during assembly, maintenance and on-site fine-tuning of fittings. The tools are intended for users who need simple, reliable instruments for tightening hex fasteners and adjusting window regulators.

Advantages

The 4 mm hex key provides a snug fit for standard hex bolts and screws, reducing slippage and wear on fastener heads. The window adjustment wrench is shaped to engage typical regulator fittings and allows controlled, incremental adjustments. Supplied as a compact two-piece set, the tools take up minimal space and are convenient to carry for service technicians or DIY users. Both tools are made to provide practical mechanical leverage for routine fastening and alignment operations.

Suitable for

• Assembly and tightening of furniture and fittings that use 4 mm hex fasteners
• Adjustment of window mechanisms and regulators
• On-site maintenance and troubleshooting of window hardware
• General repair tasks requiring a 4 mm hex key and a dedicated adjustment wrench

Key specifications

• Tool set: two pieces — 4 mm hex key and window adjustment wrench
• Hex key size: 4 mm
• Intended use: fastening hex bolts/screws and adjusting window regulator fittings
• Form factor: compact hand tools suitable for carrying in a toolkit
• Material: metal construction designed for mechanical leverage (manufacturer-specified finish not provided)

How to use

Use the 4 mm hex key by inserting the short or long arm into the hex socket of the fastener and apply controlled torque to tighten or loosen bolts and screws. For the window adjustment wrench, locate the regulator or adjustment point on the window mechanism, engage the wrench with the fitting designed for window adjustment, and turn slowly to achieve the required alignment or tension. Work incrementally and check the window operation after small adjustments to avoid overcorrection. Apply steady, even force and ensure the tool is properly seated on the fastener or adjustment point before applying torque.

Usage recommendations

Use with compatible 4 mm hex fasteners and standard window regulator fittings only. Inspect fasteners and fittings before adjustment, keep hands and reflection-free surfaces clear of pinch points, and wear appropriate hand protection if needed. Store the tools dry to avoid corrosion and maintain fit by avoiding excessive force that could deform hex profiles.
