A speed nut (1) for fastening a work piece to a stud (36) includes a fastener plate (10) defining an opening (16) on a surface. The speed nut (1) further includes a prong (18) extending inwardly from an edge of the opening (16), the prong (18) includes a root portion (42) connecting with the fastener plate (10) and a terminal end (44) defining a single-threaded hole (20) within the opening (16) and configured to ratchet over threads of the stud (36). The root portion (42) and the terminal portion (44) are arranged offset from each other such that the prong (18) plastically deforms in response to the work piece being removed from the stud (36). 种用于将工件紧固到螺栓(36)的插片螺母(1)，包括紧固件板(10)，其在表面上限定开口(16)。插片螺母(1)还包括自开口(16)的边缘向内延伸的插脚(18)，插脚(18)包括与紧固件板(10)连接的根部(42)和在开口(16)内限定单螺纹孔(20)并配置为棘合于螺栓(36)的螺纹上的末端(44)。根部(42)和末端(44)设置为彼此偏移，使得插脚(18)响应于工件从螺栓(36)移除而塑性变形。
