Compact Metric Fold-Up Hex Set

The Eklind 21172 is a seven-piece metric fold-up hex key set designed for tightening or loosening fasteners in tight spaces. Its compact size fits into small areas while still providing sufficient torque for everyday fastening tasks. The set covers metric sizes from 2 mm to 8 mm, making it suitable for precision work on bicycles, furniture, machinery and automotive components. Both professional technicians and DIY users will appreciate the portable format.

Alloy Steel Blades With Black Oxide Finish

The blades are made from alloy steel with a black oxide finish that resists corrosion and reduces glare during use. Alloy steel handles fold around the blades for protected storage and quick deployment, keeping the keys organised in a tool bag or pocket. The fold-up mechanism eliminates loose pieces and allows rapid size selection without searching for individual wrenches. This integrated handle design also provides a comfortable grip when applying torque.

4.10 Inch Maximum Arm Length

The longest arm in the set measures 4.10 inches, which determines the maximum reach and leverage available for the largest 8 mm key. Shorter arms on the smaller keys limit torque on delicate fasteners, so the set is not intended for high-torque applications or oversized bolts. Buyers who need extended reach or higher leverage for larger fasteners should consider separate long-arm hex keys instead.

Questions about this item

Will the black oxide finish on the alloy steel blades wear off and need re-treatment?

The black oxide finish protects against corrosion and reduces glare; it does not require re-treatment under normal hand-tool use.

What stops me from applying more torque once the folding handle reaches its 4.10 in arm length?

The 4.10 in arm length is the maximum leverage the fold-up design provides; beyond that the handle geometry limits further torque.

Does the alloy steel handle get hot or slip after continuous tightening?

The alloy steel handle stays at ambient temperature and the black oxide surface resists slipping during extended hand-tightening sessions.
