Turnbuckle GOST 9690

Turnbuckles to GOST 9690-71 are intended for use in mechanisms of floating craft of any type, purpose and class. Standard turnbuckles may also be used in construction and other fields.

The tensioning device is made of high-strength steel. It consists of a body with two axial holes with internal threading, into which fittings of various designs are screwed:

• hook with hook;
• ring and ring;
• fork with fork;
• eye and eye.

Any combination is possible — for example, a hook screwed in on one side and a ring on the opposite side. The body may be of open type (welded or stamped) or closed design. Both the threading of the body holes and the shanks of the screwed-in fittings must have right-hand and left-hand threads, so that tightening the wire ropes causes rotation in opposite directions.

Turnbuckles to GOST 9690-71 withstand loads from 0.1 tf to 20.0 tf depending on the design and capacity of the fitting. They are used as a tensioning mechanism; use for lifting, lowering or moving loads is prohibited.
