Patent certificate

[ Features  ]

After inserting the Rex anchor bolt into the drilled hole, the rubber packing tube is expanded and fixed in the drilled hole while rotating the nut on the top of the bolt. The high-durability/water-resistant rubber packing tube is expanded and fixed in the drilled hole, providing excellent watertight (waterproof) performance, and the high elasticity rubber packing tube absorbs vehicle impact and road vibration, improving the problem of anchor bolts being easily pulled out.

Waterproofing Rubber Expansion Anchor Bolt

(Rubber Anchor Nut, Stud Anchor, Hybrid Anchor)

Rubber Anchor Nut
Rubber Anchor Nut

[Rubber Anchor Nut] This is a world-first "Rubber Anchor Bolt" technology that incorporates rubber packing into the anchor bolt body. It is a new-tech anchor bolt developed using high-grade special rubber—equivalent to tire standards—featuring high elasticity, high rigidity, non-flammability, water resistance, and chemical resistance.

Stud Anchor
Stud Anchor

[Stud Anchor] Featuring an original fixing structure with rubber packing and three frictional protrusions, this technology prevents rotation and ensures stable fixation. Upon insertion, the outer diameter contracts, and the protrusions create a mechanical interlock. Utilizing non-flammable and water-resistant materials, it offers superior durability in fire-prone or humid environments. This is a new-tech anchor bolt designed for easy disassembly and reinstallation.

Hybrid Anchor
Hybrid Anchor

[Hybrid Anchor] This is a dual-fixing anchor bolt that integrates traditional mechanical sleeve expansion with advanced rubber expansion technology. It allows for robust installation through simple rotational tightening, eliminating the need for impact tools.

By combining primary mechanical sleeve expansion with secondary elastic rubber expansion, this innovative technology simultaneously ensures superior anchoring strength, ease of installation, and exceptional waterproofing performance.
