Carriage Bolt Anchors

Carriage bolt anchors, also known as carriage bolt expansion bolts, belong to post-installed anchoring connection products. In terms of appearance, it is usually composed of a screw rod, an expansion tube, a flat washer, a spring washer, and a nut. One end of the screw rod is threaded for fastening in cooperation with the nut; the other end is specially designed, usually open, to facilitate the expansion function during installation. The expansion tube is generally made of metal material, with a certain degree of elasticity and strength. It can expand outward when subjected to external forces, thus firmly embedding into the base material.

The application fields of carriage bolt anchors are extremely extensive.

In terms of building structures, it can be used to fix steel structures, aluminum alloy structures, etc., providing guarantee for the overall stability of buildings. For example, in the curtain wall installation of high-rise buildings, carriage bolt anchors can firmly fix the curtain wall frame on the concrete wall to resist various external forces such as wind force and seismic force. In the field of interior decoration, it is often used to fix heavy-duty lamps, air conditioning units, wall cabinets and other equipment. For some places where guardrails need to be installed, such as stairwells and balconies, carriage bolt anchors are also an ideal choice for achieving firm installation.

Compared with other types of anchors, carriage bolt anchors have numerous advantages. 

Firstly, it has a relatively high bearing capacity and can withstand large tensile and shear forces, ensuring the stability of the connected objects under various working conditions.

Secondly, the installation process is relatively simple. It does not require complex tools or professional skills, which can effectively improve construction efficiency and reduce labor costs. 

Thirdly, carriage bolt anchors have strong adaptability and are suitable for a variety of base materials, including concrete, solid bricks, hollow bricks, etc. As long as the base material meets certain strength requirements, reliable anchoring can be achieved.

In addition, its material usually has good corrosion resistance, and can still maintain stable performance in harsh environments such as humidity, acid and alkali, thus extending its service life.
