GOST 22040-76 Studs with Threaded End of 2.5d, Product Grade B

GOST 22040-76 applies to studs with a threaded end of 2.5d, product grade B, with nominal thread diameter from 2 to 48 mm. Studs are manufactured with coarse thread pitch on both the nut end and the threaded end, with fine thread pitch on both the nut end and the threaded end, with fine thread pitch on the threaded end and coarse thread pitch on the nut end, with coarse thread pitch on the threaded end and fine thread pitch on the nut end.

The design and dimensions of studs conform to the drawing and Tables 1, 2. Design 1 and design 2. Diameter d₂ is approximately equal to the pitch diameter of the thread.
