HEXAGON BOLTS, PRODUCT GRADE A Construction and dimensions Hexagon bolts, product grade A. Construction and dimensions	GOST 7805-70 (ST SEV 4727-84)

1. This standard applies to hexagon bolts, product grade A, with a thread diameter from 1.6 to 48 mm.

The standard fully complies with ST SEV 4727-84.

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

3. Thread — per GOST 24705. Thread runout and incomplete thread — per GOST 27148. Bolt ends — per GOST 12414.

3a. Radius under the head — per GOST 24670.

3b. Tolerances of dimensions, form and location deviations of surfaces, and inspection methods not established by this standard — per GOST 1759.1.

3c. Permissible surface defects of bolts and inspection methods — per GOST 1759.2.

4. By agreement between the manufacturer and the customer, bolts with a nominal thread diameter from 36 to 48 mm may be made with a thread pitch of 2 mm.

5. The head design variant is determined by the manufacturer.

5a. Bolts may be manufactured with the diameter of the plain shank portion d₁ approximately equal to the pitch diameter of the thread.

5b. For marking purposes, bolts of versions 1 and 2 may be made with a recess on the end face of the head, with dimensions that do not reduce the strength of the head; the recess depth must not exceed 0.4k.

6. Technical requirements — per GOST 1759.0.

7. The mass of bolts is given in Appendix 1.

D₁ ≤ 0.8S

h = (0.2 + 0.4)k
