The fastener includes a body and a locking pin. The body includes a base with an aperture therethrough which is aligned with a slot formed between two downwardly extending conjoined arms. The downwardly extending conjoined arms include predrive engagement notches and locking surfaces. The locking pin includes two downwardly extending flexible legs with predrive positioning protrusions. In the predriven position of the fastener, the predrive positioning protrusions are engaged by the predrive engagement notches. In the driven position of the fastener, the predrive positioning protrusions are engaged by the locking surfaces. Additionally, in the driven position, pin retention protrusions on the locking pin are engaged by mating surfaces in the base of the body. The predrive positioning protrusions are formed in a plane which is perpendicular to the plane in which the pin retention protrusions are formed.
