12-20 Cheese Head Screw

For Hand Planes – Common Frog Mounting Screw

If your plane is old and the screw holding the frog down looks like this — this is likely the one you need.

This is a 12-20 thread cheese head screw, commonly used to secure the frog to the body of many vintage hand planes.

When these strip, rust, or go missing, your frog won’t sit tight. Your adjustment won’t hold. Your plane won’t perform.

That’s the problem.
This solves it.
