GOST 1477-93 is a set screw with a straight slot and a drilled end. The main difference between a set screw and other types is the absence of a head or a cap. At its ends, there are special protrusions or recesses - splines, which strengthen the connection and fixation of structural parts.
Fastening group GOST 1477-93
Set screws with a straight slot and a drilled end according to GOST 1477-93 are made of stainless steel and belong to the stainless fasteners group.
Materials for manufacturing screws of GOST 1477-93
Screws of GOST 1477-93 are made of stainless steel grade A2. Steel grade A2 or “food grade stainless steel” is one of the most commonly used. The material is non-toxic and corrosion-resistant, which makes it suitable for use in the food and medical industries. The alloy itself does not have magnetic properties, but it can develop them during cold machining of steel.
Applications for GOST 1477-93 screws
The GOST 1477-93 screw is installed in a blind hole and tightened so that the base metal is squeezed out by this edge. Thus, due to frictional forces, the metal product stops in the hole. This quality of fastening is used in components subject to alternating and vibration loads, such as gearboxes.
It is widely used in:
- mechanical engineering,
- instrumentation,
- industrial and manufacturing sectors.
