A wrench includes a wrench body and an end stopper arrangement. The end stopper arrangement includes a turning head extended at a handle portion of the wrench body, wherein the turning head has a through turning cavity and a plurality of gripping muscles spacedly and inwardly protruded from a sidewall of the turning cavity for engaging with the corner portions of a bolt nut, and a plurality of blocking members integrally and inwardly protruded from each of the gripping muscles to partially cover an opening of the turning cavity such that when the bolt nut is inserted into the turning cavity to engage with the gripping muscles, the blocking members are adapted for biasing against a top side of the bolt nut for ensuring that the bolt nut is fittedly retained in the turning cavity without dislodgment of the wrench body.
