The expansion anchor bolt consists of several main parts: the ring cylinder, gasket, and nut. When in use, make a hole in the wall and insert the expansion bolt into the hole. When tightening the bolt, the ring cylinder will be squeezed and stretched open, and will be stuck in the hole to provide a fixing effect.
Expansion anchor bolts are widely used in the field of construction to secure supports/hangers/brackets or equipment to walls, floors, and columns. Its advantages include easy installation, good fixing effect, and the ability to withstand large tensile and shear forces, making it suitable for a variety of materials and structures.

Features:1. Easy to install
2.Wide applicability: Suitable for various concrete structures
3.There are various forms of force, including under pipe anchor bolts, internally forced anchor bolts, and expansion anchor bolts, which are suitable for different installation environments and requirements.
4.Small design stress: Due to the fact that expansion anchor bolts mainly rely on friction for fixation, their design stress is usually small, and the utilization rate of steel is low.

Application scenarios:Architecture and infrastructure: used for fixing walls, floors, columns, etc., such as connecting and fixing infrastructure such as glass curtain walls and railway bridges.
Industrial equipment: installation and fixation of various large equipment in industrial plants, lifting systems, and conveyor systems.
Daily life: installation and fixation of various pipelines, anti-theft doors and windows, fire doors, etc
