Versatile fastener
A versatile fastener including at least two flat areas formed on a cutting part, and an accommodating area disposed between any two of the flat areas. At least two cutting faces are convergent to form the accommodating area, and first and second cutting edges are respectively formed at a connection between each cutting face and flat area. In operation, the flat areas facilitate the first and the second cutting edges to promote a stable balance with the object, thereby allowing the debris to be swiftly guided out of the accommodating areas. Consequently, it is difficult to crack the object while imparting forces thereon, so as to lower the screwing resistance and the fastening torque as well as increase the combining efficiency.
