It is free library of the limited nomenclature of bolts of GOST 7798. It contains blocks and drawings of bolts of normal accuracy without a chemical covering of a class of durability 5.8 (about 2 % from bolts of GOST 7798 really put into practice).

Each block contains a text part: a designation, weight, mark of steel and the code of the drawing. At such approach the information on the inserted block is not lost even in case of its splitting into parts. 

All blocks and drawings are executed in a layer 0. Lines thickness of 0,5 mm and 0,18 mm under requirements of GOST and ISO.

The encryption of drawings is executed by analogy to system of the design documentation of Russia applied at the aviation enterprises, as the encryption of the general mechanical engineering - is insufficient for assignment of each detail of the unique code.

Creation of full commercial library of GOST 7798 will demand time. Then I shall create library of bolts of the raised accuracy (product grade A) of GOST 7805 and its free part I send for you.

Basically, for display of interest of the Russian firms small and an average level to QCAD, it is necessary to have a minimum in its structure: bolts, screws, nuts, washers, pins (see GOST_STD_PARTS.ods - marked as red), and corresponding advertising.

Large firms already have the development and works with AutoCAD, Solidworks, though 80 % of their problems can be solved with QCAD.
