1. Dimensions, unless otherwise noted: in inches; apply after finish. 2. Surface texture per ASME B46.1. 3. Conical surface of head to be concentric to "D" within 0.004 FIM. 4. "A1" is concentric to "D" within "F" FIM. Runout of "D" to "Pitch" within "Tol. X" when held on the "Pitch" of the complete threads nearest the shank and checked on the shank within one diameter of the thread runout. 5. Blended radius transition permits use in interference fit application. 6. Curved or flat edge manufacturer´s option. 7. Flute location ("K" dimension) and geometry are inspected per HFS specification E106. 8. Threads must accept a AS8879 "GO" ring gage to assure free running nut capability. AS8879 limits do not apply to threads in the fluted portion of the thread, the minor and pitch diameters may be up to 0.004 below AS8879 minimum values and major diameter may be up to 0.002 below sheet 1 values for a distance equal to the flute length plus 1.5P Max. 9. See table III. 10. Pins shall be packaged or repackaged in clear sealed bags. Each bag shall be marked with the purchaser´s and manufacturer´s complete part number. Manufacturer´s lot number, manufacturer´s or distributor´s name and the pack date. 11. See sheet 6 for usage and inactivation applicability information. 12. For dimensions not shown, see sheets 1 and 2. 13. For material, finish and lube information, see sheets 1 and 2. |
