Small yellow croaker nylon plastic expansion bolts are a type of plastic anchor used for fixing objects in materials such as masonry, brick, and concrete. These bolts are known for their high strength, durability, and resistance to corrosion, making them suitable for both indoor and outdoor applications.

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:

Nylon Material: Made from high-quality nylon, such as PA66 (polyamide), which is known for its stiffness and toughness, although slightly more brittle than PA6. It is ideal for applications requiring higher stiffness at the expense of resilience.

Expansion Mechanism: The expansion bolt consists of a screw and an expansion tube. When the screw is tightened, the cone-shaped tail expands the tube, creating a strong grip within the material.

Corrosion Resistance: Often treated with surface treatments like hot galvanizing, blackening, color-zinc, or blue white zinc to enhance corrosion resistance.

Versatile Applications: Suitable for use in concrete, brick, hollow block, drywall, and plaster. They work well in hard surfaces where no studs or beams are behind the surface.

Scope of Application

Construction: Used in construction projects for securing materials like formwork, safety barriers, and drywall tracks to concrete or masonry structures.

Home Improvement: Ideal for DIY projects and home improvements, such as hanging shelves, mirrors, and other decorative items on masonry walls.

Outdoor Applications: Due to their corrosion resistance, these bolts are suitable for outdoor applications, such as securing outdoor furniture, lighting, or garden structures.
