Preventing burnout and improving work efficiency!

Quastix looks similar to a standard cross-recessed screw, but it has a mechanism that makes it difficult to cam out. Standard cross bits can also be used. Cam out during screw tightening can lead to wasted work time and potential damage to materials. Quastix addresses these issues by suppressing cam out, contributing to improved work efficiency. [Usage Scenarios] - Assembly of wooden furniture - Assembly of metal furniture - Mass production in factories [Benefits of Implementation] - Prevention of damage to materials due to cam out - Prevention of cross-recess collapse (ream out) - Reduction of work time - Reduction of worker burden
