浮動壓鉚緊固件 A4、AS、AC

鎖定和非鎖定螺紋這些緊固件提供薄片承重螺紋，並允許對配合孔錯位進行高達 0.030 英吋的調整。 p>自鉚接功能可實現快速、簡單的組裝。使用任何標準壓力機將緊固件擠入準備好的孔中。片材一側保持齊平，緊固件永久鎖定到位。 浮動螺母的螺紋完全延伸到固定器柄中（獨特的PEM 功能），可在組裝過程中提供額外的強度和支撐）。也提供自鎖版本的緊固件。螺紋鎖定扭力性能相當於適用的 NASM25027 規範。 B」標度為88。 許多PEM AS 型和AC 自鉚式浮動緊固件符合US NASM45938/11 規格中的尺寸。請查看我們的網站，以取得完整的軍事規範和國家航空標準參考指南（NASM 公告）。
