Expansion Shell Roof Bolts
Expansion shell roof bolts are a type of fastener commonly used in construction and mining to secure heavy loads to concrete or other solid surfaces. These bolts consist of a threaded metal rod with a flared cone-shaped end that is inserted into a pre-drilled hole in the surface. When a nut is tightened onto the threaded end of the bolt, the cone-shaped end expands, pressing against the sides of the hole and providing a secure anchor point.
