What are hex keys used for?
Hex keys, also known as Allen wrenches, are used to tighten or loosen hexagonal screws and bolts. They are commonly used in furniture assembly, appliance repair, automotive maintenance, and various DIY projects.
What sizes do hex keys come in?
Hex keys come in a variety of sizes, typically ranging from small fractional sizes (such as 1/16 inch) to larger metric sizes (such as 10mm). It's important to have a set that includes a range of sizes to accommodate different screw and bolt types.
How do I choose the right hex key set?
When choosing a hex key set, consider the sizes and designs included in the set, the quality of the material (preferably hardened steel), the comfort and ease of use (ergonomic handles, smooth operation), and any additional features you may need, such as color-coded handles or size markings.
Do hex keys come with a warranty?
The warranty coverage for hex keys can vary depending on the brand and manufacturer. It's always a good idea to check the product specifications or reach out to the manufacturer directly to inquire about warranty information.
Are hex keys interchangeable with other tools?

Can I use hex keys on rusted screws or bolts?
In some cases, hex keys can be used to loosen rusted screws or bolts. However, if the rust is severe or the fastener is completely stuck, it's advisable to use penetrating oil or other rust-loosening agents before attempting to use a hex key.
How should I maintain my hex keys?
To maintain your hex keys in good condition, clean them after each use to remove any debris or dirt. You can use a soft cloth or a mild cleaning solution if necessary. Store your hex keys in a dry and organized place to prevent rust and ensure easy access when needed.
