Overview
DIN 561-B Hexagon socket head bolt is a fastener consisting of a reduced hexagonal head and a cylindrical end (socket). The set screw is designed to securely fasten parts and assemblies, which is why it has a special design feature. It is equipped with a hexagonal head. A cylindrical guide pin is provided for easy wrenching for additional secure positioning.
Strength class DIN 561-B
The strength class of a DIN 561-B bolt is the maximum applied force at which the bolt begins to fracture. DIN 561-B bolts are manufactured in strength classes 8.8. From strength class 8.8, the bolt is considered high-strength. High-strength DIN 561-B should only be purchased from trusted suppliers. It is made of alloy steel and such bolts are used for critical projects where, in addition to high loads and static loads, the DIN 561-B bolt is subjected to constant vibration.
DIN 561-B fastening group
DIN 561 bolts are made exclusively of high-strength steel and belong to the high-strength fastener group.
Materials for the manufacture of DIN 561 bolts
DIN 561 bolts are made exclusively of high-strength steel of strength class 8.8.
Areas of application for DIN 561 bolts
The DIN 561 bolt is widely used for fastening metal products; it provides reliable fixation of parts and assembly structures. Fasteners of this type are used in mechanical engineering, instrumentation, machine tool building, and can be used in construction, furniture manufacturing, and other industries.
