WebOct 8, 2024 · H (high) represents a pitch diameter that is larger than the basic pitch diameter, and L (low) represents a pitch diameter that is smaller. The number after the H or L, indicates the amount it is different than the basic pitch diameter. Each number after the H or L is equal to 0.0005, so an H3 or L3 is equal to 0.0005 x 3 or 0.0015. In engineering, we have to define the tolerances of parts to ensure a long lifespan and proper working of a machine. We can choose the fits according to the necessities and working conditions. The three main categories are: 1. Clearance fit 2. Transition fit 3. Interference fit All these come with another subset of categories, … See more With engineering fits, the tolerance will always be shown in an alpha-numeric code. For example, a hole tolerance may be H7. The capital letter signifies that we are dealing with a hole.
