ASTM A193 Scope
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

This is a video on how to rebuild your BMW X3 Transfer Case (ATC-400) I got my bearings for here: https://www.americanpowertrainwarehouse.com/bmw-x3-w-tod-atc-400-transfer-case-chain-fits-03-borg-warner-hv-086-made-in-usa/
and the Bearing Kit here: https://cobratransmission.com/bmw-x3-bearing-kit-55133001-1
UPDATE: Before you take the transfer case apart, use a cardboard drawing of the case and when you extract each bolt, stick it through the cardboard. This will guarantee that when put it back together you will put the bolts in the correct location. (You can see my cardboard cut out at 5:35 in the video)
