Abstract: PURPOSE: A torque-shear type high strength bolt is provided to presume the axial force of a high strength bolt by drawing out the correlation formula of the temperature variable of a high strength bolt. CONSTITUTION: A torque-shear type high strength bolt comprises following steps. The tightening axial force of the torque-shear type high strength bolt presumes the torque-shear type from the correlation of the length variable and the temperature variable. The axial force of the torque-shear type high strength bolt is presumed with equation N=172.333+0.699T-1.053L-0.004T. The N is the axial force(kN) of bolt, and L is bolt length(mm). The equation measures the axial force in centigrade 10 ~ 50 degrees.
