The present invention relates to a bolt for mounting a subframe of which one end connects to a subframe and the other end connects to a bracket mounted on a side member. The bolt for mounting a subframe comprises a bolt part formed in such a manner that a screw is extended from one end of a body part connected to the subframe; and a nut part, joined with a bracket, which has a coupling hole to allow a screw to be inserted and coupled. When collision load is applied, the screw is broken. According to the present invention, the nut part and the bolt part are mechanically coupled to secure enough durability, and when collision load is applied, breakage is achieved, thereby improving crashworthiness.

    본 발명은, 일단은 서브프레임으로 연결되고 타단은 사이드멤버에 장착된 브라켓에 연결되는 서브프레임 마운팅용 볼트에 있어서, 서브프레임으로 연결되는 몸체부의 일단에서 스크류가 연장되어 형성된 볼트부; 및 상기 브라켓에 접합되며, 스크류가 삽입되어 결합되는 체결홀이 형성된 너트부;를 포함하고, 충돌 하중이 가해지면 상기 스크류의 파단이 이뤄지는 것을 특징으로 한다. 상기와 같은 구성을 갖는 본 발명은 너트부와 볼트부가 기계적으로 결합되어 충분한 내구성을 보장하되 충돌 하중이 가해지면 파단이 이뤄져서 충돌 성능을 향상시킬 수 있다.
