Features of Expansion Screws

Strong Fastening Force

Expansion screws consist of components such as screws, expansion tubes, and nuts. By tightening the nuts, the expansion tubes expand inside the holes and press against the hole walls, generating strong friction and fastening force. This enables them to firmly fix objects to the base materials, with excellent load - bearing capacity.

Easy Installation：No complex installation tools or professional skills are required. Just use a drill to make holes, insert the expansion screws into the holes, and tighten the nuts to complete the installation. The operation is simple, which greatly saves installation time and labor costs.

Wide Adaptability

They can be applied to various types of base materials, including concrete and brick walls. Whether it is a hard concrete wall or a relatively soft brick wall, reliable fixation can be achieved, meeting the requirements of different construction scenarios.

Convenient Disassembly

When disassembly is needed, simply unscrew the nuts and remove the expansion screws. This causes minimal damage to the base materials, facilitating subsequent renovation and adjustment.

Rust - Proof and Durable

Most expansion screws are made of stainless steel or metal materials with anti - rust treatment, having good corrosion resistance. They can maintain stable performance in complex environments such as humid and acidic - alkaline conditions, with a long service life.
