Tactile Screw Drive Check
A tactile check method for 100% inspection.
The drive check is a tactile method for checking the drive of a screw, which reliably detects drive defects.
With this method, the drive of a screw is tested using commercially available bits.
Bit check method
During the tactile drive check, a rotating device equipped with 10 test bits is installed in the measuring and testing system. The rotation mechanically presses the bit 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.
