After finishing work, the handle unscrews to the lowest position on the scale. The torque range is different for different torque wrenches. The small ones allow, for example, the adjustment from 5 to 25 Nm, and the larger ones in the range from 30 to 300 Nm....
This paper examines the relationship between the preload and no-load drag torque of ball screws. Based on a new equation to calculate the normal contact load between balls and the screw raceway under no external load, a new correlation between preload and no-load drag torque is proposed. ...
This equation can also predict the withdrawal of screws from fiberboard with K = 57.3 (metric) or 3,700 (inch– pound) for the face and K = 44.3 (metric) or 2,860 (inch– pound) for the edge of the board. Withdrawal resistance of screws from particle board is not significantly diffe...

Utilizing bolt class information, the clamp load of the bolt can be determined with the following equation. P = St x As Where: P: clamp load St: bolt tensile strength As: tensile stress area The value for tensile stress area can be determined from: ...
Accordingly, the bolt head displacement Δ𝑑𝑛Δdn is calculated using Equation (2) in the normal direction. Next, as shown in Figure 3b, when the torque T is applied to the bolt head, the normal force 𝐹𝐶FC can be calculated as 𝑇/𝑎T/a, where a represents the distance ...
