Festool Individual Hex Keys
Replacing a missing key from your tool kit? Festool hex keys let you buy the individual size you need.
Use them on matching hex socket screws when adjusting guides, fittings or machine accessories. Check the screw size and required reach first, then choose the right key rather than buying another complete set.
What Are Festool Hex Keys Used For?
- Replace a missing or worn key in your machine kit so a loose hex socket fixing does not hold up the next job.
- Adjust fences, stops and accessory brackets secured by hex socket screws, using the size specified for the fitting.
- Reach recessed screws on workshop equipment where the key needs enough length to engage fully without catching the surrounding housing.
- Fit a matching ball end key into an awkwardly positioned screw for angled access, then use the straight end for final tightening where accessible.
Choosing the Right Festool Hex Key
Buy for the screw you have, not the size that looks close enough.
1. Match the Exact Size
Check the machine manual or fitting specification before ordering a Festool individual Allen key. Metric and imperial sizes are not interchangeable; a slightly undersized key can round the socket before the screw comes loose.
2. Straight End or Ball End
If access is straight and the screw needs firm tightening, use a straight hex end fully seated in the socket. Choose a Festool ball end hex key where angled access is needed, but do not use its smaller contact area to force a seized screw.
3. Reach and Working Clearance
If the screw sits behind a guard or inside a bracket, check both reach and room to turn the key. A longer arm helps with access, but it is no reason to overtighten a small fixing.
4. Check the Drive Profile
A hex key is not a substitute for Torx or a screwdriver. Check the screw recess first; use Festool Screwdrivers for matching screw heads, or browse Festool Fastening Tools if the job needs a different drive tool.
Who Uses Festool Hex Keys?
Joiners, kitchen fitters and workshop maintenance teams use individual keys to replace missing sizes and keep the correct adjustment tool with each machine. For a broader kit, check the Festool Allen Keys (Hex Keys) range rather than assuming one key covers every fitting.
Choose the Right Festool Hex Key for the Job
Match the key to the fixing size, access and tightening task.
| Your Job | Hex Key Type | Key Features |
|---|---|---|
| Replacing one missing machine adjustment key | Individual key in the specified size | Correct across-flats dimension and enough reach for the fitting |
| Tightening an accessible hex socket screw | Straight hex end | Full engagement with the screw socket for controlled tightening |
| Turning a screw beside an obstructing bracket | Ball end key, where available | Angled access within the key manufacturer's stated limits |
| Adjusting a recessed fitting | Key with sufficient arm length | Reach to seat fully, with clearance to turn without fouling the housing |
Common Buying and Usage Mistakes
- Choosing the nearest size rather than the exact size leaves play in the socket and can round the screw. Confirm the specified dimension before applying force.
- Using a ball end to break loose a seized fixing risks damaging the key or socket. Use a fully seated straight end and investigate the seized fixing rather than forcing it.
- Pushing a key into a socket packed with dust prevents full engagement. Clean out the recess before turning the screw.
- Adding a pipe for extra leverage can snap the key or strip the thread. Follow the equipment's tightening instructions and use a suitable torque tool where a torque value is specified.
Individual Hex Keys vs Hex Key Sets vs Hex Driver Bits
Individual Hex Keys
Buy an individual key when one size is missing or you want a dedicated adjustment key kept with a machine. It avoids duplicating a whole set, but only covers fittings of that size.
Hex Key Sets
Choose a set for maintenance work across several machines or fittings. You have more sizes to hand, although the set still needs the correct metric or imperial coverage for your equipment.
Hex Driver Bits
Use a matching hex bit with a suitable hand driver or torque tool for repeated fastening or specified torque settings. Check holder clearance and bit rating; a driver assembly may not fit where an L-shaped key will.
Maintenance and Care
Wipe Off Dust and Residue
Clean the working ends after use, especially around adhesives or resin. Build-up can stop the key seating properly in a small screw socket.
Keep It Dry and Accounted For
Dry the key before storage and keep it in a labelled holder or the machine's designated storage position. Loose keys are easily lost among larger Festool Hand Tools.
Replace Damaged Ends
Check for rounded corners, twisting or cracks before use. Replace a damaged key rather than grinding it down and risking an inaccurate fit.
Use the Specified Adjustment Tool
Before servicing machinery or changing Festool Router Bits, isolate the power and follow the machine manual. Use a hex key only on matching hex socket fittings, not as a substitute for the specified collet spanner.

Festool Hex Keys FAQs
What is the difference between an allen key and a hex key?
They are common names for the same type of tool: a six-sided key used to turn internal hex socket screws. When choosing Festool Allen keys, the important details are the exact size, reach and end shape, not which name is used.
What sizes do Festool hex keys come in?
The available sizes depend on the individual keys listed in the range. Check each product's stated size in millimetres and match it to your equipment manual or fixing specification. Do not assume every size is available individually or choose a near match.
What are ball end hex keys for?
A ball end lets you turn a hex socket screw with the key held at an angle, useful when a bracket or housing blocks straight access. The permitted angle depends on the key. Use the straight end for higher-load tightening or loosening wherever access allows.
Are Festool hex keys any good?
They are a practical choice when replacing a specified Festool adjustment key or keeping the correct size with your equipment. The brand does not make an undersized key safe to use: check the fit, seat it fully and replace it if the working end becomes rounded.
Where are Festool tools made?
Festool has manufacturing operations in Germany and the Czech Republic, but that does not establish the origin of every hand tool or accessory. For an individual hex key, check its packaging or ask ITS to confirm the country of origin for the exact product.
