ISO 4027 Set screw with socket head

  Setting screw ISO 4027 with internal hexagon, threaded along the entire length and tapered end. The tapered end has a special shape that serves to fix the elements relative to each other.

Materials used to manufacture ISO 4027 tapered end screws

  The ISO 4027 screw is made from a variety of materials:

• Steel, which can optionally be coated with zinc
• or ISO 4027 stainless steel A2 and A4

Area of application

     The ISO 4027 set screw is used whenever there is a need to fasten workpieces. Additional reliable fixation of the mutual positioning is achieved if the inner surfaces of the parts are made with projections with a corresponding recess. 
     This fastener is most often used in machine tools, as well as in the automotive and aircraft industries. It is used in conjunction with nuts and washers of the appropriate size (see ISO 4027) and material.
     The range of applications also depends on the material of manufacture and the coating of the product:

• Zinc coating on steel protects against corrosion if the fastener is to be used in aggressive environments
• Stainless steel, grade A2. The material is non-toxic and corrosion-resistant, which makes it suitable for use in the food and medical industries.
• A4 is the second most popular grade; it also has similar properties to A2, but is more resistant to corrosion in aggressive environments and acids due to the addition of molybdenum.
