More info
Description / Abstract:
This Standard covers the American National Standard practice for Die Buttons, Variable, Press Fit including dimensions, tolerances, nonmenclature, sizes and shapes. These die buttons are classed as "Extra Precision".
The Standard covers die buttons in two styles: solid and split; and two types: headless and head type. Round die buttons are in the solid style only and shaped die buttons are in the split style only. The Standard covers round, oblong, square and rectangular hole die buttons for up to one inch diameter maximum pierced hole size.
Headless die buttons are intended primarily for retention in the die block or retainer by press fit and for installations in thick die blocks in counterbored holes. Head type die buttons are intended for retention in the die block or retainer by press fit and/or by the shoulder action of the head and for applications requiring increased bearing area for the die buttons.
