Pan head hexagonal expansion bolts combine the smooth appearance of round head bolts with the holding characteristics of expansion bolts. They usually consist of a round head, a hexagonal driving part and an expansion tube. The expansion tube unfolds within the wall as the bolt is tightened, providing a secure fixing.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Aesthetics: The round head design allows the bolt to sit flush with the surface after installation, providing a neat appearance. High Strength: The hexagonal drive section allows for greater torque to be applied with a wrench or power tool, making it suitable for high load applications. Quick Installation: Expansion bolts are quick and easy to install, improving construction efficiency. Wide applicability: Suitable for a wide range of materials including concrete, brick and wood. Corrosion resistance: Some models are made of stainless steel, making them suitable for wet or corrosive environments.

Scope of Application

Building structure fixing: for fixing windows, door frames, brackets and other building components. Machinery and equipment installation: fixing machine bases, pipes and other equipment to ensure their stability and safety. Furnishing and decorating: for fixing decorations on plasterboard walls, hanging objects and installing furniture, etc. Electrical and plumbing systems: fixing wire channels, pipes and fittings.
