Thread Limit H3 at Raymond Gillespie blog

Thread Limit H3. Selecting an h limit for plated parts is relatively easy. Learn how to choose the right tap size and h limit for different classes of fit and thread tolerances. H and l limits are used for inch size ground thread taps. H (high) represents a pitch diameter that is larger than the basic pitch diameter, and l (low) represents a pitch diameter that is smaller. Normal tap tolerance is iso 2 (6h), which generates an average quality fit between screw thread and nut. Our detailed chart ensures precise thread fit and optimal performance for your needs. The letter g will be followed by the letter h to designate above basic (l below basic) and a numeral to designate the pitch diameter limits. Each h limit represents 0.0005 inches over basic pitch diameter. See tables of unc and unf tap limits for 1b, 2b and 3b fits. The number after the h or l, indicates the amount it is different than the basic pitch diameter. G h3 indicates a ground thread tap. The best way to visualize the differences in screw thread classes of fit is shown on the bar graph in figure 2. Each number after the h or l is equal to 0.0005, so. There are (3) established classes of thread, designated in the unified series by adding: A for screws and b for nuts (or other intenal.
