💡 Why do you need socket extensions?
Socket extensions give you extra reach to bolts buried deep in an engine or machine.

• Extensions help you reach recessed and hard-to-get fasteners
• They let your ratchet clear hoses, brackets, and parts
• Longer extensions work well with breaker bars for leverage
• Wobble and locking extensions add more control
