ISO 4017, defines hex head fully threaded bolts. These bolts are fully threaded along their entire body length, providing maximum grip and holding performance in short connection distances. The fully threaded design offers the advantage of widespread use in metal-to-metal connections, flanged systems, assembly lines, and automation components. ISO 4017, technically DIN 933 It is largely compatible with the standard. The difference between them usually manifests in tolerance levels. The product is preferred in fastening applications requiring high torque and is safely used in the manufacturing, assembly, and maintenance sectors.

The two standards are very similar; the difference is usually seen in measurement tolerances. They are equivalent in terms of technical function.
Provides maximum grip and torque transmission at short connection distances. It is the ideal solution for flange connections and compact systems.
Made of carbon steel for manufactured bolts, generally to provide corrosion resistance electrogalvanized, hot-dip galvanizing (HDG), nickel, Geomet or black oxide coatings are applied.
