Screw axial
WebbThe relation between applied torque and axial force - or load - in a bolt can be calculated in this general equation as. T = K F d (1 - l/100) (1) where . T = wrench torque (Nm, lb f ft) K = constant that depends on the bolt material and size . d = nominal bolt diameter (m, ft) F = axial bolt force (N, lb f) l = lubrication factor (%) Webb螺旋轴（screw axis） n_m. 螺旋轴属于第二类对称操作，会产生手性异构体。 螺旋轴是旋转轴和平移操作的结合。 螺旋轴对称操作被记作 n_m ，其中 n 为旋转轴的阶数， m 为全平移程 n\vec \tau 与平行于旋转轴方向的最小晶矢 \vec t 的比值，即有
