Core Drill Expansion Anchor

Instructions for Use: 

First, drill a hole of the appropriate size in the fixed object using an impact drill (hammer). 

Then, insert the bolt and expansion sleeve into the hole and tighten the nut to make the bolt, expansion sleeve, 

and mounting parts tightly integrated with the fixed object.

Product Advantages: 

Resistant to acids, alkalis, low temperatures, aging, and heat; no creep; water stains at room temperature; 

good flame retardancy; excellent shock resistance.

Working Principle: 

After driving the expansion bolt into the hole in the ground or wall, tighten the nut on the expansion bolt with a wrench.

The bolt moves outward, while the outer metal sleeve remains stationary. 

The large end of the bolt then expands the metal sleeve, filling the entire hole. At this point, the expansion bolt cannot be pulled out.
