摘要： The present invention is directed to an internally threaded prevailing-torque type self-locking fastener which employs a patch of fused thermoplastic material as the locking element and which satisfies the functional torque requirements of both IFI 100/107 (1987) and IFI 101 (1987). In accordance with the present invention the fastener comprises a metal body having a bore extending to its opposing ends, the bore having a threaded surface; a patch of polymeric material applied and fused to a portion of the threaded surface; and the fastener meeting the prevailing-torque characteristics specified in both IFI 100/107 (1987) and IFI 101 (1987). The invention is also directed to a process wherein an internally threaded fastener is processed by first applying and fusing a polymeric resin material to at least a portion of the fastener's threaded surface and thereafter conditioning the frictional properties of the fastener such that its prevailing torque performance characteristics meet both IFI 100/107 (1987) and IFI 101 (1987).
摘要翻译：本发明涉及一种内螺纹主导扭矩型自锁紧固件，其使用熔融热塑性材料块作为锁定元件，并且满足IFI 100/107（1987）和IFI 101（1987）的功能转矩要求）。根据本发明，紧固件包括具有延伸到其相对端部的孔的金属体，孔具有螺纹表面; 施加并熔合到螺纹表面的一部分的聚合物材料片; 并且紧固件满足IFI 100/107（1987）和IFI 101（1987）中规定的主要扭矩特性。本发明还涉及一种方法，其中通过首先将聚合物树脂材料施加到紧固件的螺纹表面的至少一部分并随后调节紧固件的摩擦性能来处理内螺纹紧固件，使得其主要的扭矩性能特征符合IFI 100/107（1987）和IFI 101（1987）。
