Stainless Steel Wedge Anchor/Through Bolt/Expansion Bolt

A car repair gecko, also known as an expansion bolt or expansion bolt, is a fixture used to create a firm connection on a wall or other surface. It usually consists of bolts, nuts, gaskets and outer bushing, etc. The outer bushing expands when the nut is tightened, squeezing the inner wall of the hole to form a strong connection.

Working principle

The working principle of the car repair gecko is to use the expansion of the outer casing to fix the object. During installation, the bolt is inserted into the pre-drilled hole, and then the nut is tightened. The groove or cut of the outer casing is squeezed during the nut tightening process, so that it is tightly fitted to the inner wall of the hole to form a strong connection.

Application scenario

Car repair geckos are widely used in building and structural engineering for fixing objects to concrete, brick walls, stone or other solid surfaces. Common applications include installation brackets, guardrail, pipe supports, ceiling hooks, electrical equipment, etc.

advantage

Suitable for a wide range of solid surfaces such as concrete and brick walls.

Easy installation: no special tools required.

Adjustable tightening: Suitable for different applications.

High tensile and torque-bearing capacity: provides a strong holding force.

Installation precautions

Before installing the car repair gecko, it is necessary to ensure that the cleanliness and depth of the hole meet the requirements to ensure the quality of the expanded pipe. It is also important to choose the right embedment depth, because increasing the embedment depth will increase the tension.
