Thread Restrict or pitch diameter Restrict is a typical useful for classifying the tolerance on the thread pitch diameter for faucets. For imperial, H or L restrictions are used which designate how many units of 0.0005 inch over or undersized the pitch diameter is from its simple worth, respectively. Hence a tap designated with an H Restrict of three, denoted H3, might have a pitch diameter 0.
