Mainly used in concrete and dense natural stone, steel structure, railing, elevator lines, machines, brackets, doors, stairs, exterior wall finishes, Windows, etc., suitable for the role of medium load fixing
Hexagon casing gecko: also known as floor expansion bolts, mainly used in concrete and dense natural stone, steel structure, railings, elevator lines, machines, brackets, doors, stairs, exterior wall veneers, Windows, etc., suitable for medium load fixing. This product has the advantages of simple installation, convenient and fast, is a new product to replace the welding, embedded bolts and other cumbersome processes.

The product is composed of wall tube, hex bolt, striped nut and flat pad. The thread of the bolt is fully buckled.

Hexagon tubes are widely used in various structural parts, tools and machine parts. Compared with the round tube, stainless steel special-shaped tube generally has a larger moment of inertia and section modulus, has a larger bending and torsion resistance, can greatly reduce the weight of the structure, save steel

Hexagon casing gecko is a special threaded connector used to fix pipe support/suspension/bracket or equipment on wall, floor and column. Hexagonal casing geckos are commonly used in building basements to protect pipes or to facilitate pipe installation rings

Material and surface treatment of hexagonal casing gecko

Material :Q235 Surface treatment: color plating

Actually bolt design, material has been chosen, it should be here in a separate say it again because the author thinks that the material is really very important, most bolts are plain carbon steel or alloy steel, this is the normal situation, and bolts may be used in high corrosive environment temperature changes or larger environment, or extreme temperature environment, so ordinary carbon steel or alloy steel is not suitable , for example, ordinary carbon steel materials will become brittle at extreme low temperatures, easy to produce brittle fracture without warning. However, if it is applied to high temperature environment, ordinary carbon steel will creep, that is, in the case of no loosening of the thread, the pre-tightening force of the bolt will be reduced, easy to loosen or fatigue failure.
