The Marksman 30 Piece Hex Key Set is designed for DIY enthusiasts and homeowners who require a comprehensive range of fasteners for assembly, repairs, and maintenance. Its primary benefit is the inclusion of both Metric and Imperial measurements, ensuring you have the right tool for hardware regardless of its origin. A key caveat is that while these keys are durable for general home and hobbyist use, they are not intended for high-torque professional automotive or industrial mechanical applications that might exceed the limits of hardened steel.

The smallest size is 0.7mm in the Metric set and 0.028 inch in the Imperial set.
Yes, they feature a black oxide finish which is specifically designed to resist corrosion.
While durable, these are intended for general DIY and home maintenance; professional-grade automotive work often requires high-tensile specialty tools.
The largest sizes are 10mm for the Metric set and 3/8 inch for the Imperial set.
The folding carry case features labeled slots; simply match the size stamped on the key to the corresponding slot in the case.
Double-check whether the bolt requires an Imperial or Metric key, as sizes can be very similar.
Ensure the key is fully inserted into the socket. If it still slips, the screw head may be stripped and require extraction tools.
Utilize the long-arm end of the Imperial keys to gain the necessary reach and leverage.
To keep your Marksman hex keys in top condition, wipe them down with a dry cloth after use, especially if they have been exposed to moisture or grease. If you are working in a damp environment, a light coating of machine oil can help maintain the integrity of the black oxide finish. When selecting the correct size, if you feel significant "play" or movement between the key and the bolt head, stop immediately and check the next size up. Forcing a slightly-too-small key will strip both the tool and the screw head.
