Expansion Bolts are a commonly used fastener that is typically used to secure various types of structures to base materials such as concrete and brick walls. Expansion bolts come in a wide variety of sizes, and different sizes of expansion bolts are suitable for different installation environments and needs.

These screws are usually made of stainless steel, carbon steel, or other metallic materials. Surface treatments may include zinc plating, nickel plating, passivation, etc. to improve corrosion and wear resistance. The chemical composition of the stainless steel material should be within the range specified in the steel group, the chemical composition of A2 and A4 stainless steel is specified in the following table .

Advantage:

High strength: Expansion bolts usually have high tensile and yield strengths and can withstand large loads.

Easy to install: the installation process is simple, just drill holes, insert bolts and tighten the nuts to realize the fixing.

Wide applicability: suitable for a wide range of materials, including concrete, brick and wood.

CORROSION RESISTANCE: Expansion bolts made of stainless steel provide excellent corrosion resistance and are suitable for long-term applications in wet or chemical environments.

Adjustability and reusability: Expansion bolts can be adjusted for tightening strength and can be easily disassembled after loosening, making it easy to repair and replace equipment.

Scope of Application

Building structure fixing: Expansion bolts are used to fix windows, door frames, brackets and other structural components.

Machinery and equipment installation: fixing machine bases, pipes and other equipment to ensure their stability and safety.

Furnishing and decorating: for fixing decorations, hanging objects and installing furniture, etc.

Electrical and plumbing systems: fixing wire channels, pipes and fittings.
