Specifications:
The document outlines specifications for leader pins used in guided ejection applications. The pins are of a straight style with a 15˚ tapered lead-in. The material used is AISI 1117, with the core and head having an approximate hardness of 25 HRC and the surface 58-62 HRC. The pins are designed for a press fit of 7/8”.

Dimensions and Tolerances:
General dimensions are provided with nominal diameters ranging from 3/4” to 3”. Tolerances for diameter (d), length (l), and other parameters (m, t, b, k) are specified with precise measurements.

Catalog Numbers:
The document includes a detailed table listing catalog numbers for various leader pin sizes and lengths. The table is organized by diameter and length, providing specific catalog numbers for each configuration.

Recommendations:
For custom leader pins, users are directed to refer to templates in section X. Additionally, for leader pins with a 7/8” press fit, further details can be found on page B-21.

Key Data from Tables:
The tables provide a comprehensive list of catalog numbers for different pin sizes, indicating the availability of specific configurations. The dimensions and tolerances are critical for ensuring proper fit and function in applications.
