BSA Bolt, oil pipe union to crankcase (5/16" Unified Coarse × ½")

PN · 21-1973
This is a bolt that secures the oil pipe union to the crankcase, 5/16 inch Unified Coarse thread by 1/2 inch. It shows up in crankcase figures, including the crankcase/generator area, so it's part of the hardware holding the oil feed line where it meets the crankcase casting.
