1) With adoption of CUP SCREW, no assembly washers are required.
2) CUP SCREW provides high maximum tightening torque, with excellent loose-proof effect.
3) CUP SCREW helps further increase the loose-proof effect in combination with the use of TAPTITE screw.
4) With use of CUP SCREW, there is no more problem of damage to tightened object material.
1) In the case where cost reduction is intended from fastening using washers, CUP SCREW is a good choice.
2) In some cases requiring high fastening force for protection against loosening, CUP SCREW is one of the best solutions.
