Overview
GOST 14724-69 is a flip bolt with a ring, with a full or partial metric. It is used to connect parts and assemblies in production machines, devices, as well as in industrial, engineering and construction industries. The GOST 14724-69 screw is also used for rigging devices and for mounting various elements in walls and ceilings together with anchors.
Strength class of GOST 14724-69
The strength class of a bolt in accordance with GOST 14724-69 is the maximum applied force at which the bolt begins to fracture. GOST 14724-69 bolts are manufactured in strength classes 4.6 and 8.8. From strength class 8.8, the bolt is considered high-strength. High-strength GOST 14724-69 should be purchased only from trusted suppliers. It is made of alloy steel and such bolts are used for critical projects where, in addition to high loads and static loads, GOST 14724-69 bolts are subjected to constant vibration.
Fastening group of GOST 14724-69
Depending on the material of manufacture, bolts of GOST 14724-69 are divided into groups:
- Brass fasteners - bolts made of brass
- Stainless fasteners - bolts are made of stainless steel
- High-strength fasteners - bolts are made of steel of strength class 8.8.
Materials for manufacturing bolts in accordance with GOST 14724-69
GOST 14724-69 bolts are made of the following materials:
- Steel, strength class 4.6. Can be additionally coated with zinc. Zinc (Plated) protects against corrosion if the fasteners are to be used in aggressive environments
- High-strength structural alloy steel, strength class 8.8. It can be additionally coated with plated zinc.
- Stainless steel grades A2 and A4. Allows the use of fasteners at significant temperature changes and in aggressive and humid environments.
Scope of application of GOST 14724-69 bolts
GOST 14724-69 bolts are used to connect parts in production machines, as well as in industrial, machine-building and construction applications. They are also used for rigging devices and for mounting various wall and ceiling elements.
