How to select the correct oversized tap for a repair job?
Select an oversized tap like the CHICAGO-LATROBE H13 / 1B when the original thread is damaged or needs a looser fit. Measure the existing hole diameter and thread pitch (e.g., 5/16"-18 UNC). Use a plug chamfer for through holes and ensure the tap material matches your workpiece hardness.
