Small Yellow Croaker Plastic Expansion Bolt

Small Yellow Croaker Plastic Expansion Bolt

We are a factory-direct manufacturer of the versatile and reliable “Small Yellow Croaker” plastic expansion anchor, also known as a nylon expansion bolt or screw anchor plug. This light-duty fastener is designed to provide a secure and stable fixing point in a variety of solid base materials, including concrete, brick, blockwork, and stone. Its unique fish-like design with anti-rotation fins ensures a strong grip, preventing the anchor from spinning in the hole during installation. Available in popular metric sizes (M6, M8, M10), it is an essential component for construction, home decoration, and general DIY projects.

Product Details

The anchor’s effectiveness comes from its clever design and high-quality materials.

  • Design: The anchor features a split body with prominent external fins or “wings”. When a screw is driven into the central channel, the two halves of the anchor are forced apart. This expansion presses the fins firmly against the inner walls of the pre-drilled hole, creating a powerful friction-based hold. The fins also act as an anti-rotation mechanism, ensuring the plug does not spin while the screw is being tightened.
  • Material: The anchor plugs are manufactured from high-quality, durable plastics such as PA (Nylon) or PE (Polyethylene). These materials offer an excellent balance of flexibility (to allow for expansion) and toughness (to resist tearing and aging), ensuring a long-lasting and reliable anchor point.
  • Accompanying Screws: These anchor plugs are designed to be used with screws. We can supply them with matching Q235 carbon steel screws of various lengths (from 20mm to 300mm) to suit your specific application.

Product Features

Our plastic expansion anchors are a popular choice due to their reliability and ease of use:

  • Strong Anchoring Force: The expansion mechanism provides a secure grip in solid masonry materials for light to medium-duty loads.
  • Anti-Rotation Fins: The “wing” design prevents the anchor from spinning in the hole during screw installation, making for a quick and frustration-free process.
  • Durable Material: Made from high-grade PA/PE plastic, the anchors are resistant to aging and degradation, ensuring a long service life.
  • Versatile Application: Suitable for a wide range of fastening tasks in both professional construction and home DIY projects.
  • Cost-Effective Solution: An economical and effective method for creating secure anchor points in solid walls and floors.

Simple Installation Guide

  1. Drill the Hole: Use a masonry drill bit of the correct diameter corresponding to the anchor size (e.g., a 6mm bit for an M6 anchor). Drill to the required depth.
  2. Clean the Hole: Thoroughly clean the drilled hole of all dust and debris using a brush or blower.
  3. Insert the Anchor: Push the plastic anchor plug into the hole until its collar is flush with the surface of the wall.
  4. Position and Fasten: Place your fixture over the anchor, insert the appropriate screw through the fixture and into the anchor plug.
  5. Tighten the Screw: Tighten the screw with a screwdriver or drill. As the screw advances, the anchor will expand to create a secure hold. Do not overtighten.

Primary Applications

These plastic anchors are ideal for a multitude of light-duty fastening applications, including:

  • Hanging pictures, mirrors, and clocks.
  • Mounting shelves, curtain rods, and blinds.
  • Securing light fixtures, electrical conduit clips, and junction boxes.
  • Fastening brackets, small cabinets, and bathroom accessories.
