ASME B18.3:2003 pdf download.Socket Cap,Shoulder, and Set Screws,Hex and Spline Keys.
Gages and gaging procedures are included in Mandatory Appendix 1. For coated products, use GO gages identical in design and tolerances to those shown in Mandatory Appendix I, except having minimum dimensions equal to minimum sizes of keys and bits shown in Tables 8 and 9. respectively. Due to possible buildup of the socket, coated products may not accept a standard hex or spline key.
2.1.1 Hexagon Sockets. Hexagon sockets shall conform with the specifications given in Table 6.
2.1.2 SplIne Sockets. Spline sockets shall conform with the specifications given in Table 7.
2.2 Threads
Threads on all screw products covered by this Standard shall be in accordance with ASME B1.1 for the series and class specified in the notes to the respective product dimensional tables.
Acceptability of screw threads shall be based on Systern 22, ASME Bit, except where otherwise specified in Note (14) of Table 5A.
2.3 Quality Assurance
l’roducts will be furnished in accordance with ASMI 1318.18.1M, with the thread acceptability to Inspection Level C, unless otherwise specified.
2.4 Dimensional Characteristics
Products shall conform to the dimensions indicated in the respective tables. The designated characteristics defined within the notes of each product table shall be inspected in accordance with ASME 1318.18.2M. For nondesignated dimensional characteristics, the provisions of ASME B18.18.1M shall apply. Should a nondesignated dimension be determined to have a variance, it shall be deemed conforming to this Standard if the user, who is the installer, accepts the variance based on fit, form, and function considerations. Where verifiable in- process inspection is used in accordance with ASME B18.18.3M or ASME l318.18.4M, the final inspection level sample sizes of those respective standards shall apply.
