1. Dimensions in inches and to be met after finish. 2. Surface texture per ASME B46.1. 3. "A" concentric to "D" within 0.010 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. 4. Flute location ("K" dimension) and geometry are inspected per HFS specification E106. 5. Threads must be 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 may be up to 0.002 below sheet 1 values for a distance equal to the flute length plus 1.5P max. 6. Blended radius transition permits use in interference fit application. 7. See table III. 8. Pins shall be packaged or repackaged in clear sealed bags. Each bag shall be marked with purchaser´s and manufacturer´s complete part number. Manufacturer´s lot number, manufacturer´s or distributor´s name and the "pack" date. 9. See sheet 6 for usage and applicability information. 10. The "B" suffix is inactive for new design. "S" suffix parts supersede "B" suffix parts. The "B" suffix indicates CROSS-LOK feature. Refer to SC7000 for CROSS-LOK feature dimensional requirements. CROSS-LOK feature not available for nominal diameter numbers: 5, 6, & 12. For all 0.0156 & 0.312 oversize pins. Only complated pins with HEX RECESS shall be modified into the CROSS-LOK configuration when so indicated by the "B" suffix. 11. "DS" code is valid for -10 diameter only. 12. For dimensions not shown, see sheets 1 and 2. 13. For material, finish and information, see sheets 1 and 2. 14. For dimensions not shown, see sheets 1 and 2. 15. For material, finish and lube information, see sheets 1 and 2. 16. See table V. |
