GOST 15589-70 bolt with full thread - it is one of the most common hardware in a variety of promishlenosti, especially popular in the automotive industry and instrumentation, where they are used to fasten the massive parts of metal structures.
Hexagonal bolt is a rod with a thread (metric or inch) along the entire length and hexagonal head. In some cases the bolt may have a straight slot. Used in conjunction with nuts, washers of the appropriate size
Strength class GOST 15589-70
Bolt strength class GOST 15589-70 is the maximum applied force, when using which the bolt begins to break. Bolts DIN 933 are manufactured in strength classes from 5,8 to 12,9. From strength class 8,8 bolt is considered high-strength.
High-strength bolt GOST 15589-70 to buy only from verified suppliers. It is made of alloy steel and such bolts are used for responsible projects where besides high and static loads, GOST 15589-70 bolt is subject to constant vibration effects. Especially relevant such bolts will be in the construction of bridges, instrumentation, as well as in structures that are located near the objects that are subject to vibration effects.
Bolt stainless GOST 15589-70 also has its own strength classifications:
- 50 - Soft steel (500 MPa)
- 70 - cold forming steel (700 MPa)
- 80 - high-strength steel (800MPa)
Fastening group GOST 15589-70
Depending on the material of manufacture hexagonal head bolt GOST 15589-70 divided into a variety of fastening groups:
- High-strength fasteners
- Brass fasteners
- Stainless fasteners
- Polyamide fasteners
Materials of bolts GOST 15589-70
Technical characteristics of GOST 15589-70 bolt with full thread also directly depends on the material of manufacture of the bolt:
GOST 15589-70 bolt is made of:
1. Steel. The range of strength class of this material is 5,8-12,9. In addition, this material can be additionally coated with:.
- Zinc for better protection against corrosion, if the product is planned to be used in aggressive conditions.
- Dacromet this type of coating does not cause hydrogen embrittlement on steel.
- Platkovy zinc has similar properties to obichnoy zinc, but the outside of the bolt is matte.
- Yellow zinc - similar in properties to obichnoy zinc, but the color of the bolt is yellow.
2. Hot zinc products with this coating are the most resistant to corrosion.
3. stainless steel A2 A4 A5. Allows you to use the fastener at significant temperature differences, in aggressive and humid environment. Such material does not require coating.
4. Brass. Brass bolts are used if the system is subjected to regular dynamic, vibration and cyclic loads.
Scope of bolts GOST 15589-70
Bolt GOST 15589-70 used in bolt and screw connections in construction, automotive, industrial and industrial spheres with washers and nuts of appropriate sizes. also often used with anchor sleeves, as well as hammered anchors.
The area of use of GOST 15589-70 also depends on the material of its manufacture:
- Steel, cold galvanized, galvanized bolt is used in the operation of objects of industrial production.
- Steel, hot-dip galvanized - construction and installation works, both external and internal.
- Brass - constructions with higher requirements to decorative characteristics, electrical devices, sanitary devices.
- Stainless steel - A4 - food industry; A2 - appliance constructions and constructions.
- High-strength steel - construction of multi-storey buildings, road structures, construction of bridges and subways.
