Wave thread form |
| 摘要 |
A wave thread form for threaded fasteners includes multiple thread pitches along a generally helical path, and includes multiple wave thread portions each deviating from a straight-line helical path, with adjacent wave thread portions along the helical path being separated by standard thread portions extending along the generally straight-line helical path. |

1. A thread form for a threaded fastener having a thread extending along a generally helical path for multiple thread pitches, said thread form comprising:
multiple wave thread portions each defining a thread segment in which the thread has a cross-sectional shape and deviates from a straight line helical path; and a standard thread portion between adjacent wave thread portions, each standard thread portion defining a thread segment having a cross-sectional shape and extending along a straight line helical path, wherein the cross-sectional shape of said wave thread portions is the same as the cross-sectional shape of each standard thread portion. |
