Mechanical Properties of ISO 898-1 Fasteners - Made of Carbon Steel and Alloy Steel - Part 1: Bolts, Screws and Studs with Specified Strength Class - Normal Thread and Fine Thread Thread

Developed by the International Standards Organization (ISO), the ISO 898-1 standard describes the mechanical and physical properties of bolts, screws and studs made from carbon steel and alloy steel. This standard has been published in our country by the Turkish Standards Institute with the following title: TS EN ISO 898-1 Mechanical properties of fasteners - Made of carbon steel and alloy steel - Part 1: Bolts, screws and studs with specified strength class - Normal thread and fine pitch thread.

These tests are carried out at an ambient temperature of 10 to 35 degrees and certain fasteners such as bolts, screws and studs that meet the standard's requirements are evaluated. If the tests are carried out at higher or lower temperatures, the test sample may not retain its mechanical and physical properties.

The general characteristics of bolts, screws and studs to which this standard is applied are as follows:

  • Made of carbon steel or alloy steel
  • With metric thread as described in ISO 68-1 standard
  • With certain coarse and fine threads
  • Diameter and slope combinations comply with ISO 261 and ISO 262 standards
  • Screw thread tolerances comply with ISO 965-1, ISO 965-2 and ISO 965-4 standards

This standard does not apply to non-tensioned setscrews and similar threaded fasteners. In addition, standard requirements are specified for properties such as welding ability, corrosion resistance, resistance to shear stress, torque and clamp force performance and fatigue resistance.It was menu.

In short, bolts, screws and studs must meet all applicable mechanical and physical properties, at ambient temperature, regardless of what tests are performed during production or final inspection.

Among the services provided by our organization within the framework of metallic testing services, there are also ISO 898-1 standard tests.
