Select Quantity
How It Works

Toolbox Widget keeps your 1/2" metric sockets clearly labeled and easy to grab. Each size stem plugs in fast, locks into place, and gives you a clean, easy-to-identify setup. The bold white numbers on the black stem stand out instantly so you can spot the right size without digging. Every stem is height-selectable—you simply cut it to the length you need and snap it in—making this one of the most customizable and reliable socket labeling systems on the market.
