Amendment No. 4 to GOST 22037-76 “Studs with threaded end of 1.6d length. Product grade A. Construction and dimensions”. Approved and put into effect by Resolution of the USSR State Committee for Standards dated 28.04.88 No. 1204. Effective date — 01.01.89.

1. This standard applies to studs with a nominal thread diameter from 2 to 48 mm, manufactured:

• with coarse pitch thread on the nut end and the threaded end;
• with fine pitch thread on the nut end and the threaded end;
• with fine pitch thread on the threaded end and coarse pitch thread on the nut end;
• with coarse pitch thread on the threaded end and fine pitch thread on the nut end.

2. The design and dimensions of studs shall conform to those shown in the drawing and in Tables 1, 2.

Type 1

Type 2

d₂ is approximately equal to the pitch diameter of the thread
