In industrial production, driving screws is a common yet critical operation; tightening quality directly affects product quality and safety. However, when operators make mistakes or when the process is not standardized, the same bolt is occasionally tightened twice, introducing various risks. To cope with this problem, making use of the advanced functions of a smart electric screwdriver has become an important solution.

Danikor smart electric screwdrivers show unique advantages in preventing double tightening. The core idea is the “angle-monitoring” method. During a normal tightening cycle, the screwdriver records the rotation angle of the bolt; this angle falls inside a reasonable range because the bolt has to rotate a certain amount to go from loose to the target torque. If an operator tightens the same bolt again, the bolt has already reached the target torque, so the additional rotation angle will be obviously smaller. A Danikor smart electric screwdriver can sensitively detect this change.
In actual use, a lower-angle limit can be set in the Danikor controller. When the measured tightening angle is smaller than this limit, the system alarms immediately and reminds the operator to stop the duplicate tightening. This limit is not fixed; it must be adjusted for real working conditions. Factors such as material hardness, screwdriver type, and working environment all influence the tightening angle. By collecting and analysing on-site data, a suitable lower-angle limit can be found for each application.
In addition, Danikor smart electric screwdrivers also monitor torque, time, and other parameters during the tightening process. These parameters complement one another and form a multi-directional monitoring system. For example, when a bolt is tightened twice, the angle becomes smaller, but the torque may still lie within the normal range (or change only slightly), whereas the time parameter may reveal an abnormal operation. Through multi-parameter comprehensive monitoring, the screwdriver can judge more accurately whether the tightening process is normal, thereby effectively preventing double tightening.
In real production, the anti-double-tightening function of Danikor smart electric screwdrivers not only improves product-quality stability, but also reduces the risk of equipment damage and production-efficiency loss caused by repeated tightening. By providing accurate control of the tightening process, it offers enterprises a reliable quality-assurance method. Under the trend of intelligent manufacturing, the application of Danikor smart electric screwdrivers supplies new ideas and methods for solving traditional tightening problems and pushes industrial production toward higher efficiency.
