Lighten the load by having a way to take fewer tools to jobs away from your workbench. High-quality steel alloy construction ensures that the 4pc socket driver adapter set will last for years. In fact, with the Craftsman forever guarantee, you will get a new adapter if one ever breaks. The chrome finish creates a professional look while protecting your tools from corrosion.
