| ①,1. No extrusion of excess metal beyond the apex of the point resulting from thread rolling shall be permissible. A slight rounding or truncation of the point is desirable. ②,The width of flat at crest of thread shall not exceed 0.004 in. for sizes up to and including No.8, and 0.006 in. for large sizes. ③,For screws in these nominal lengths and shorter, use Type AB screws specified in Table 40. |
