FAQs

What is the smallest and largest size in this set?

The set includes keys starting at 1.5 mm up to 10 mm.

Can I use the ball-end for high-torque applications?

It is recommended to use the ball-end for positioning and low-torque turning, then finish tightening with the straight-end for maximum grip.

Are these tools rust-proof?

While the S2 steel is wear-resistant, it is not stainless. Keep them away from moisture and store in a dry place to prevent surface oxidation.

What is the advantage of S2 steel?

S2 steel is harder and tougher than typical chrome vanadium or carbon steel, meaning it is less likely to round off or deform over time.

Are the keys individually marked with the size?

Yes, they are colour-coded for quick identification, and the sizes are generally marked on the casing or the keys themselves.

Troubleshooting

Key does not fit bolt head

Verify the bolt is metric; ensure the key is fully inserted into the socket. If paint/coating thickness makes it feel tight, ensure you are using the correct size.

Bolt is slipping

Stop immediately. The bolt or the key may be worn. Try a fresh key or use the standard non-ball end for better grip on a damaged bolt head.

Pros and Cons

Pros

  • High-quality S2 steel offers great durability and longevity
  • Ball-end feature allows for versatile angling in tight spots
  • Colour coding makes size selection extremely efficient
  • Ergonomic handle improves control and reduces hand fatigue

Cons

  • Smallest sizes require careful handling to avoid bending or stripping
  • Plastic storage casing may occupy more space than a simple metal ring
  • Ball-end is less effective than standard ends for extremely high-torque loosening

Setup, Compatibility & Care

To ensure the longevity of your S2 steel Allen keys, store them in their provided holder after every use to prevent loss and keep them organized by size. Keep the keys dry and clean; while S2 steel is robust, wiping them down with an oily rag after use will prevent rust and keep the finish looking like new. The set is compatible with all standard metric hexagonal screws ranging from 1.5mm to 10mm. Avoid using extensions or 'cheater bars' on the smaller keys (1.5mm to 3mm), as the torque applied can easily snap these thinner tools. If the keys become greasy during use, simply wipe them with a mild degreaser and a cloth to restore their non-slip surface.
