Phillips screwdriver bit No. 1, 44 mm long, 4 mm half round shank - Delvo DLB2126

The larger the recess, the more torque runs across the four flanks of the blade, so with size No. 1 the grade of the steel is what counts. This NK4D bit is made in hardness grade H, the hardest grade Nitto Kohki assigns to screw sizes from 1 to 3 mm.

Benefits

• Hardness grade H, matched to the higher load of size No. 1
• 44 mm overall length for direct driving without needless extension
• 11 mm blade length, the flanks bear over the full depth of the recess
• Collar at 20 mm sets a fixed insertion depth in the H4 holder
• Minimised runout of the bit axis thanks to full in house manufacturing

Applications

Screw joints on housings, brackets and sheet metal parts where the screw already calls for noticeable torque, for example in equipment building, control cabinet work and final assembly.
