Thepair 1A and 1B define the loosest fit; 3A and 3B define the tightest. Class 1A/1B threads are used for rough work, for example, where some thread damage can be expected or conditions are very dirty. Class 2A/2B threads are for general use. Class 3A/3B fasteners are used for applications requiring an extra degree of precision.
FineThread Series (UNF/UNRF) is commonly used in precision applications. Because of the larger tensile stress areas, they have high tension strength. However, a longer engagement is required for fine thread applications than for coarse series threads to prevent stripping. 3 ⁄ 4 - 10: 0.6850: 0.302: 0.334: 3 ⁄ 4 - 16:
