Common in broadcast, military, and telecommunications 2-post racks. Common Sizes: #10-32, #12-24, or metric M6 threads.

However, I can help you understand what the standard covers and where you can legally obtain it.

The EIA-310D standard has been a cornerstone of the electronics industry for decades, providing a widely-adopted framework for the design and manufacture of electronic components. First published in the 1950s, the standard has undergone several revisions, with the most recent update being published in 2014. The standard covers a range of topics, including component sizes, shapes, and terminal configurations, with the goal of ensuring interoperability and compatibility across different manufacturers and applications.

Because of this 0.625" - 0.625" - 0.500" repeating sequence, rack rails usually feature tick marks or numbers to indicate where a Rack Unit begins and ends. Types of Rack Holes Under EIA-310-D

Demystifying the EIA-310-D Standard: The Universal Blueprint for Server Racks and Enclosures

The EIA-310D standard, published by the Electronic Components Industry Association (ECIA), provides specifications for the physical dimensions and mechanical characteristics of electronic components, including resistors, capacitors, and inductors. This paper provides an overview of the history of the EIA-310D standard, its technical requirements, and its impact on the electronics industry. We examine the benefits and limitations of the standard, as well as its relevance in the modern era of miniaturization and surface mount technology.
