Tactile screw drive check
A tactile check method for reliably testing the drive of a screw.
The drive check (bit check) is a tactile method for checking the drive of a screw, which reliably detects drive defects.
In this procedure, the drive of a screw is tested using a standard bit (e.g. hexalobular socket, hexagon socket to internal multi-tooth).
Tactile drive testing eliminates the risk of the production coming to a standstill due to a defective drive, as this procedure corresponds to the installation process of the screw.
Bit check method
During the tactile drive check, a rotating device is installed in the machine, which is equipped with 10 test bits. As the device rotates, the bit is mechanically pressed through a guide into the drive of the screw.
If the bit cannot be pressed completely into the drive, the screw is recognized as a bad part by a sensor and rejected. In the best case scenario, our customers provide bad samples so that the automatic testing machine can be optimally adjusted to the defect. There are almost no limits in terms of drive technology. From hexalobular socket, hexagon socket to internal multi-tooth and other drive types can be tested in a wide range of sizes and variants.
After the tactile drive test, you can be sure that the drive of your screws has been 100% tested for free movement and screwability.
