  • Description
  • Four piece bolt expansion "usually refers to an expansion bolt (also known as an expansion anchor bolt) used for fixing or connecting, which fixes the bolt in concrete or other substrates through expansion during installation. The design of this bolt enables it to provide stronger tensile and shear resistance when subjected to force.

    During the installation process, the bolt is screwed into the pre drilled hole. As the bolt rotates, the expanding part of the bolt will expand outward, tightly clamping the hole wall to achieve a stable fixing effect. Usually used in applications that require high-strength fixation, such as buildings, bridges, and mechanical equipment.
