If there's any tool set you need in the garage it's a reasonable set of Hex Wrenches. This nine piece set of hex wrenches covers all your bases from 1.5mm to 10mm. Each wrench has a ball driver tip on the long side, and its short side is nicely chamfered so it slids into bolt heads easily. 

The set contains wrenches of the following sizes:

• 1.5mm, 2mm, 2.5mm
• 3mm, 4mm, 5mm
• 6mm, 8mm, 10mm
