The Ford Model T Combination Wrench with part number T-5893 is a classic tool designed specifically for these vintage vehicles. Here's a breakdown of its features and uses:

Features:

• Combination Design: This wrench combines two functionalities in one tool.
  • One end has an open-ended wrench head for grabbing and turning nuts of various shapes within a size range.
  • The other end features a box-end head designed specifically for spark plugs and cylinder head bolts. The box-end design provides a more secure fit and reduces the risk of rounding off corners compared to an open-ended wrench.
• Common Sizes:
  • The open-end size is 1 inch, which was commonly used on Model T components.
  • The box-end size is likely 5/8 inch, perfect for removing and installing spark plugs and tightening cylinder head bolts on Model T engines.
• Steel Construction: Made from durable steel for functionality in car maintenance tasks.

Benefits:

• Versatility: The combination of open-ended and box-ended heads offers functionality for various tightening and loosening tasks on the Model T.
• Secure Spark Plug Removal/Installation: The 5/8" box-end provides a good fit for spark plugs, protecting them from damage during the process.
• Efficient Head Bolt Tightening: The same box-end allows for secure tightening of cylinder head bolts.

Applications:

• Model T Maintenance: This wrench was a go-to tool for various tasks on the Ford Model T, including:
  • Loosening and tightening nuts and bolts of various sizes (using the open-ended head).
