ISO 14579 Bolt with cylindrical head and socket head

   ISO 14579 is a bolt with a cylindrical head and an internal hexagon. A cylindrical head bolt is a fastener consisting of a metal stud with an incomplete metric thread and a cylindrical head with an INBUS (hexagonal) spline.

Strength class ISO 14579

     The strength class of an ISO 14579 bolt is the maximum applied force at which the bolt begins to fracture. ISO 14579 bolts are manufactured in strength classes from 8.8 to 10.9. From strength class 8.8, the bolt is considered high-strength. High-strength ISO 14579 should be purchased only from trusted suppliers. It is made from alloy steel and such bolts are used for critical projects where, in addition to high loads and static loads, the ISO 14579 bolt is subjected to constant vibration. Such bolts will be especially relevant in bridge construction, instrumentation, and in structures that are located near objects subject to vibration.

Fastening group ISO 14579

     Depending on the material of manufacture, ISO 14579 bolts are divided into groups:

• High-strength fasteners - bolts made of steel with a strength class of 8.8 or higher.
• Stainless fasteners - fasteners made of stainless steel.

Materials for the manufacture of ISO 14579 bolts

     ISO 14579 bolts are available in the following materials:

• High-strength structural alloy steel. The high strength class allows the bolts to be used for highly loaded connections. Which can be additionally coated with zinc and yellow zinc.
• Stainless steel grades A2 and A4. Allows the use of fasteners at significant temperature changes and in aggressive and humid environments.

Areas of application for ISO 14579 bolts

     The screws are used in aerospace construction, machine building and instrumentation. To install an element, it is necessary to prepare the thread. A strong fixation is ensured by a nut or washer of the specified technical parameters.
