Bahco are a Swedish tool manufacturer founded in 1886.  They are best known for inventing the adjustable spanner.  They make quality tools in their own factories across Europe and are now owned by the same parent company as Snap-On tools.

Allen, or hex keys, are an increasingly common fitting.  We propably have Ikea to thank for that.  For me as a keen cyclist I've always had and used multiple sets.  This set feature "edge plus" which is a Bahco feature that helps prevent the tools rounding the bolt heads.

Each size is colour coded for easy identification and has a simple push fit into the holder to keep everything secure.  The kit includes the following sizes:

1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10mm.

Standard on one end, ball end on the other for angled access.

Made in Spain.
