Overview
GOST 10620-80 is a self-tapping screw with a semi-recessed head, which can be used to connect elements made of sheet steel and paste, as well as fix various elements on sheet steel. The GOST 10620-80 standard specifies two types of ends, form C and form F. The first form - C - denotes a product with a sharp end, the second - with a blunt end - respectively, form F. The differences do not end there. It is allowed to perform with two types of slots - cross (Ph) and posidrive (Pz)
Fastening group GOST 10620-80
Self-tapping screws GOST 10620-80 are most often made of stainless steel and belong to the group of stainless fasteners.
Materials for the manufacture of self-tapping screws GOST 10620-80
Self-tapping screws GOST 10620-80 are made of the following materials:
- Steel, which is additionally coated with white and black zinc, which protects against corrosion, if the fasteners are intended to be used in aggressive environments.
- A2 and A4 stainless steel allows the use of fasteners at significant temperature changes and in aggressive and humid environments. The material does not need coating.
Scope of use of GOST 10620-80 self-tapping screws
The GOST 10620-80 self-tapping screw has become widely used in industry, as well as in construction. It is used for connecting structural elements, as well as for installation in wood, plastic without pre-drilling a hole, as well as in metal. but with pre-drilling.
A feature of GOST 10620-80 is additional slots at the end that increase the drilling torque. Thus, the installation will be made even easier and faster.
