Types of Craftsman Sockets
Craftsman sockets come in multiple variations designed to meet different job requirements.
Standard (Shallow) Sockets
These are the most common and are ideal for applications where space is limited and the bolt does not extend far beyond the surface.
Deep Sockets
These sockets provide extra depth to reach nuts on long bolts or recessed areas.
Impact Sockets
Made from high-strength, heat-treated steel with a black oxide finish, these are built for use with impact wrenches and air tools.

Universal (Swivel) Sockets
These sockets feature a joint that allows flexibility at different angles, useful for hard-to-reach fasteners.
Spark Plug Sockets
Designed specifically for spark plugs, these sockets include rubber or magnetic inserts to hold the plug securely during installation or removal.
Choosing the Right Craftsman Socket Set
When selecting a Craftsman socket set, consider the following:
- Drive Size Compatibility: Match your socket with the ratchet or wrench drive size.
- Measurement System: Choose between SAE (imperial) and metric based on the equipment you’re servicing.
- Depth and Accessibility: Use deep sockets for recessed nuts and shallow sockets for confined spaces.
- Material and Finish: Chrome vanadium sockets resist rust and corrosion, while black oxide sockets are ideal for impact tools.
- Marking Visibility: Craftsman sockets feature laser-etched size markings, ensuring long-term readability.

Maintenance and Usage Tips
- Use the correct torque: Apply proper torque levels using a torque wrench to avoid damaging fasteners.
- Keep sockets organized: Store them in a labeled case or rail to prevent loss and ensure quick access.
- Clean regularly: Wipe off grease and debris to maintain grip and accuracy.
- Avoid mixing systems: Using a metric socket on an SAE bolt (or vice versa) can round off fasteners.
- Inspect for wear: Replace worn sockets immediately to prevent slippage.
