Special Drive Recesses

This is the product for the special driving parts that have critical points to be kept inaccessible to users for protecting product functions or for the sake of safety and thus require the screws that cannot be loosened by commercially available bits.

ドライバビットの挿入性を高めた特殊駆動部です。駆動部に設けた傾斜がビットの入りを助け、挿入時に発生する作業トラブルを低減します。作業性の向上、締結品質の向上を実現します。

十字穴上部に段形状を設けることにより、締結時に発生する塗装剥がれを防止する駆動部です。塗装剥がれによる補修（締め直し）が不要になります。

No concentration of stress because of the structure from 6 lobes, solving the problem of damage to products due to collapse of drive hole and come-out (floating of bit from the recess) during scrwe fastening. Realizes accurate fastening, with effective transmission of torque.

No concentration of stress because of the structure from 7 lobes, solving the problem of damage to products due to collapse of drive hole and come-out (floating of bit from the recess) during scrwe fastening. Realizes accurate fastening, with effective transmission of torque.

This is the product for the special driving parts that have critical points to be kept inaccessible to users for protecting product functions or for the sake of safety and thus require the screws that cannot be loosened by commercially available bits.

This is a special driving part to be used at critical points where screws should not be loosened by users for protecting the product functions or for the sake of safety.

Cross recesses were often crushed during fastening with bits and resulted in poor working efficiency. Once a cross recess is crushed, the workpiece must be modified or scrapped. These problems can be solved by this new recess.
