在难以加工的区域创建螺纹——您无法到达工件的背面，或者材料太薄而无法攻丝。为了获得强大的抓地力，这些螺母具有扭曲的螺纹，会增加与螺栓的摩擦力。因为它们用两个铆钉安装，所以当您拧紧螺钉时它们不会旋转。 但是，这些螺母确实会在它们的固定器内移动，这样您就可以以微小的角度安装螺栓；使用它们与偏离中心的零件对齐。所有产品均符合尺寸和材料的军用准则。

镀镉螺母在工业和盐水环境中具有抗腐蚀能力，但在450° F以上时会失去耐腐蚀性。镀镉还增加了润滑性，使这些螺母易于安装。

A286 不锈钢 螺母耐腐蚀。 镀银不锈钢螺母可承受高达800° F的温度。镀银还增加了润滑性并防止因螺母和螺栓之间的摩擦引起的卡死。

润滑的螺母顺利拧到螺栓上。
