A strap fastener set, capable of providing a reading of a tensile force exerted thereon, includes a strap fastener for winding a first strap and a gauge provided between the strap fastener and a second strap. The gauge includes a cylinder tied with the second strap. The cylinder includes a window defined therein and a scale provided thereon along the window. A first ring is secured to the cylinder. A spring is put in the cylinder. A rod extends past the ring through the spring for connection with the strap fastener. A second ring is secured to the rod so that it is moved relative to the cylinder so as to compress the spring against the first ring when a tensile force is exerted on the straps. The second ring includes an indicator formed thereon for cooperation with the scale so as to provide a reading of the tensile force.
