Concrete nail type plastic expansion anchors are engineered for secure fastening in concrete and masonry applications. These small wall plugs feature easy deformation properties that ensure reliable anchoring through friction-based self-locking mechanisms.

The expansion screw system consists of a screw and expansion tube. When tightened, the conical screw tail moves axially through threads, generating substantial radial pressure against the expansion tube. This creates a friction self-locking effect between the wall, expansion tube, and cone, delivering superior fixation performance.

Available in high-performance materials: PE (Polyethylene), PP (Polypropylene), and Nylon for optimal strength and durability.
