Hefei SENOTECH New Materials Co., Ltd is proud to introduce our Factory Direct Expansion Plugs with Ribbed Design, crafted from premium PA66 Nylon and available in a complete range of sizes with matching screws. Designed for heavy-duty applications, these expansion plugs deliver exceptional holding power while being lightweight, corrosion-resistant, and easy to install. Our direct factory pricing ensures you get the best value without compromising quality, making them an ideal choice for contractors, distributors, and industrial users worldwide.
Each plug features a unique ribbed exterior that expands radially when the screw is driven, creating a tight, secure grip inside the mounting hole. The ribs also prevent rotation during installation, ensuring consistent performance every time. Made from PA66 Nylon (polyamide 66), these anchors offer excellent temperature resistance, electrical insulation, and long-term durability, even in humid or chemically aggressive environments.
Key Features & Benefits:
- Ribbed Design: The external ribs expand uniformly to provide strong friction locking against the substrate, minimizing slippage under load.
- PA66 Nylon Material: High tensile strength, UV resistance, and excellent fatigue endurance – outperforms ordinary polypropylene or polyethylene plugs.
- Heavy-Duty Load Capacity: Suitable for mounting shelves, cabinets, handrails, furniture, and industrial fixtures. Maximum pull-out load can reach up to 50 kg (depending on size and substrate).
- Complete Sets: Each plug comes with a corresponding zinc-plated carbon steel screw of matching length, eliminating the need for separate hardware sourcing.
- Full Range of Sizes: Available in diameters from 5 mm to 12 mm and lengths from 25 mm to 80 mm. Both metric and inch versions can be customized.
- Easy Installation: Simply drill a hole, insert the plug, and tighten the screw. No special tools or pre-cutting required.
- Versatile Applications: Works in concrete, brick, hollow block, drywall, and solid stone. Suitable for both indoor and outdoor use.
- Custom Options: Color, packaging (blister pack, polybag, bulk), and labeling can be tailored to your brand requirements.

Frequently Asked Questions (FAQ)
-
Q: Can these plugs be used in hollow walls?
A: Yes, the ribbed design allows expansion against the inner cavity of hollow blocks or drywall. However, for optimal holding, we recommend using toggle bolts for extremely thin panels. Our plugs work best in solid materials like concrete and brick. -
Q: Are screws included with every plug?
A: Yes, each plug is supplied with a matching zinc-plated carbon steel screw. You can also request alternative screw materials (e.g., stainless steel) or longer/shorter screws as a custom option. -
Q: What is the temperature range for PA66 nylon?
A: PA66 typically performs well from -40°C to +110°C (-40°F to +230°F). It offers good resistance to oil, grease, and many chemicals, but avoid prolonged exposure to strong acids. -
Q: Do you offer different colors?
A: Standard color is natural white (unpainted). Custom colors (like black, gray, or custom RAL) are available on request for minimum order quantities. -
Q: What packaging options are available?
A: We offer bulk polybags, branded blister packs, plastic boxes, or shrink-wrapped bundles. Private labeling is also welcome. -
Q: How do I determine the correct size for my application?
A: As a rule of thumb, the plug diameter should match the drill bit size, and the plug length should be at least as long as the thickness of the item being mounted plus the wall material. For heavy loads (e.g., shelves >30 kg), we recommend 10 mm or 12 mm plugs with longer screws. -
Q: Are samples available before bulk order?
A: Yes, we can provide samples (cost of sample plus shipping). The sample fee will be deducted from your first bulk order. Please contact us for details. -
Q: Can these plugs be used outdoors?
A: PA66 nylon has good UV resistance but may degrade over years of direct sunlight. For outdoor applications, we suggest using a UV-stabilized version or painting the plug. The screw is zinc-plated; for high-corrosion environments, request stainless steel screws.
