M16 Expansion Shell Rock Bolts

M16 Expansion Shell Rock Bolts are crucial elements in stabilizing rock formations in various industries, from mining to civil engineering.
They are used to reinforce and support rock structures to prevent them from collapsing or shifting, which can pose a serious threat to workers and structures.
There are several types of rock bolts, each designed for specific applications. Here are some common rock bolt applications and types you should know.
These rock bolts consist of a steel tube and an expansion shell that is inserted into a drilled hole in the rock. A cone-shaped wedging expansion shell is connected to the tube and expanded by using a mechanical tool or hydraulic pressure. This creates a compressive force that anchors the bolt into the rock, providing additional support and stability.
