ASME B18.8.2:2020 pdf free download.Taper Pins, Dowel Pins, Straight Pins, Grooved Pins, and Spring Pins (Inch Series).
2.1.2.3 Unhardened Ground Dowel Pins. This variety oldowel pin shall have ground cylindrical sides with both ends chamfered. Dimensions are given In Table 6.1.1-1.
2.1.3 Straight Pins. Straight pins shall have ungroursd, straight cylindrical sides with both ends definitely cham. fered on chamfered straight pins and with both ends having broken corners or being slightly chamfered on square end straight pins. Dimensions are given in Table 7,1.1.1.
2.1.4 Grooved Pins. Grooved pins shall have unground, straight cylindrical sides with three or more swaged or extruded grooves equally spaced around the periphery to displace material beyond the basic pin diameter. Both ends of the pin are normally crowned or chamfered. Several types of grooved pins are available, including headed versions, grooved drive studs, and grooved Thead cotter pins, to satisfy various design considerations. Upon installation, the material displaced by the grooves is forced back into the grooves and reacts against the sides of the hole to promote retention of the pin or stud. Dimensions of the various types of groove pins are given In Tables 8.2.1-1 through 8.2.2-2, grooved drive studs are shown In Table 8.2.1-2, and grooved T•head cotter pins are covered in Tables 8.11-3 and 8.53-3.
2.1.5 Spring Pins. Spring pins shall have straight cylindrical sides with both ends chamfered. They are available in two basic types, reflecting slotted construction and coiled construction, and the latter In standard duty, heavy duty, and light duty series to suit various design requirements. Slotted-type spring pins having a single wall and coiled-type spring pins having multiple walls are formed or wrapped from strip stock to a diameter larger than basic and hardened In accordance with para, 9.6. Upon installation the pin diameters contract and the spring reaction against the sides of the hole tends to retain the pin. Dimensions of slotted-type spring pins and coiled-type spring pins are given in Tables 9.4.4-1 and 9.4.4-2. respectively.
3 GENERAL DATA FOR TAPER PINS
3.1 Diameters
3,1.1 Major Diameter. The malor diameter, A, of both commercial and precision classes of pins, specified in Table 3.1.1-1, Is the diameter at the large end and is the basis for the pin size.
3.1.2 Diameter at SmaLL End. The diameter at the small c-nd of pins. B, is a function of the length and should be specified as a reference dimension for determining drilled hole size. (See Nonmandatory Appendix A.) It shall be computed by multiplying the nominal length of pin by the factor 0.02083 and subtracting the result From the basic pin dIameter.
