E When press−fit section is not required, specify N = 0. • When you wish to freely specify the overall length (L dimension) and diameter of the press−fit part, order using GPSL/GPS−XL ( D P.805 ).
E Recommended mold temperature for the usage of a precision leader pin and bushing is 80°C or less because of little clearance between them. ( D P.788 ) E Temper color (heat treatment color) may not be applied to the tip. Despite differences in appearance, it can be used without any problem.

■ Method of installing the straight leader pin ● When the die plate is very thick, the straight type can be set as shown in the drawing, enabling machining to be performed easily. Specify the N dimension to match the thrust.
