Get the Right Allen Key for Every Job
Our selection includes individual keys in metric and imperial (SAE) sizes, ranging from small 1.5mm keys for electronics to larger 10mm options for heavy-duty jobs. We also offer folding sets that keep multiple sizes organised in one compact tool, ideal for toolboxes or workshops. Sets with colour-coded handles or size markings make it easy to find the right key quickly.
We stock trusted brands like Bondhus, Crescent, Wera, and Supercraft, known for durable, heat-treated steel keys that resist wear and rounding. These high-quality tools are built to last through countless projects.
When selecting allen keys, arm length is crucial – longer arms provide better leverage for stubborn fasteners, while shorter keys are ideal for tight spaces. Ball-end hex keys allow working at angles up to 25 degrees, making them perfect for awkward positions. For frequent use, consider sets with magnetic tips or ergonomic handles to reduce hand fatigue.
Many sets come with storage cases or holders to keep tools organised and prevent loss. Some folding sets include both metric and imperial sizes, offering maximum versatility in one compact tool.
Frequently Asked Questions
What's the difference between metric and imperial allen keys?
Metric keys are measured in millimetres (e.g., 3mm, 5mm), while imperial keys use inches (e.g., 1/8", 3/16"). Most Australian furniture uses metric fasteners, but older machinery or American-made products may require imperial sizes.
How do I know which size allen key I need?
Try different sizes until you find a snug fit – the key shouldn’t wobble in the socket. Most sets include common sizes, covering most household and mechanical needs.
