2.1 Sockets

In accordance with the provisions set forth in the notes to the respective dimensional tables, screws shall have hexagon or spline sockets as designated by the purchaser.

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 1, except having minimum dimensions equal to minimum sizes of keys and bits shown

in Tables t and 9, respectively. l)ue to possible buildup of the socket, coated products may not accept a standard hex or splinc

kec

2.1.1 Hexagon Sockets. Hexagon sockets shall conform with the specifications given in Table 6.

2.1.2 SpUne 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 System 22, ASME B1.1. except where otherwise specified in Note (14) of Table 5A.

2.3 Quality Assurance

Products will be furnished in accordance with ASME B18.18.IM, 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 B18.18.2M. For nondesignated dimensional characteristics, the

provisions of ASME B18.18.IM 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 B1818.4M, the final inspection level

sample sizes of those respective standards shall apply.
