ISO4017 Hex Bolts
ISO 4017 Hex Bolts are fully threaded hexagon head bolts designed for applications requiring complete thread engagement and flexible fastening solutions. Manufactured according to ISO 4017 standards, these bolts feature continuous threads along the entire length of the shank, allowing precise adjustment during assembly and providing reliable clamping performance in various connection conditions. Compared with partial thread hex bolts, the full thread design offers greater installation flexibility, especially when different clamping thicknesses or shorter engagement lengths are required.
With a standard hexagonal head for easy tightening and a fully threaded body for secure connection, ISO 4017 Hex Bolts are widely used in machinery, equipment manufacturing, steel structures and general industrial assemblies. They are available in stainless steel, carbon steel and alloy steel materials with different strength classes and surface finishes to meet various application requirements. Through controlled manufacturing processes, including cold heading, thread rolling and inspection procedures, we ensure consistent dimensions, accurate threads and reliable performance for industrial fastening applications.

The difference between ISO4017 and DIN933:
DIN933 is the German standard, ISO4017 is the international standard, and the EU standard EN ISO 4014. The two are different in the size of the opposite side s and diagonal e of the outer hexagonal head, such as M10, M12, M14M22, and ISO4017 is smaller than DIN933. There is little difference in other specifications. The M10 and M12 are the most commonly used.
Quality Control of ISO4017 Hex Bolts
Quality control of ISO 4017 Hex Bolts is carried out throughout the entire manufacturing process to ensure consistent dimensions, accurate threads and reliable mechanical performance. As fully threaded hexagon head bolts, particular attention is given to thread quality, thread length accuracy and the connection performance between bolts and matching nuts. The production process begins with raw material inspection, including verification of material grade and chemical composition. During manufacturing, key parameters such as head dimensions, bolt length, thread profile and surface condition are controlled through in-process inspections. Thread rolling technology is commonly used to improve thread strength and ensure smooth engagement, while thread gauges are applied to verify thread accuracy according to required specifications.
Mechanical tests, including tensile strength testing, hardness testing and dimensional inspection, are performed according to applicable standards and customer requirements. Surface treatments such as zinc plating, hot dip galvanizing or other coatings are also inspected to confirm coating quality and corrosion protection performance.
Application of ISO4017 hex bolts:
ISO 4017 Hex Bolts are used in a wide range of industrial fastening applications due to their fully threaded design, flexible installation characteristics and compatibility with standard metric assemblies. The selection of material and strength class depends largely on the working environment, load requirements and corrosion conditions of the application.
For general mechanical assembly and equipment manufacturing, carbon steel ISO 4017 Hex Bolts with lower strength classes are commonly selected for their cost efficiency and reliable fastening performance. Higher strength grades such as 8.8, 10.9 and 12.9 are preferred for heavy-duty machinery, steel structures, transportation equipment and applications requiring higher tensile strength and load-bearing capacity.
Stainless steel ISO 4017 Hex Bolts, including A2 and A4 grades, are widely used in environments where corrosion resistance is important. A2 stainless steel bolts are suitable for general outdoor equipment, food processing machinery and industrial applications, while A4 stainless steel bolts provide enhanced corrosion resistance for marine environments, chemical equipment and coastal installations.
