Product Description

Moisture-Proof Nylon Four-Wing Knot Wall Anchor Plastic Expansion Plug for Bathroom Plasterboard Fixtures

Product Description

The M4 x 40mm Nylon Four-Wing Knot Expansion Wall Plug is a moisture-proof plastic fastening solution engineered for bathroom and damp environment applications on plasterboard surfaces. The anchor features a four-wing expansion body made from water-resistant PA6 nylon that will not rust, corrode, or swell in humid conditions, making it the ideal choice for towel hooks, robe hooks, and bathroom accessory mounting. When the M4 screw is driven in, the four wings fold outward behind the plasterboard, forming a secure knot-lock that resists pull-out even under repeated towel tugging. Installation requires drilling a 6mm hole, inserting the anchor until flush, and driving the screw to deploy the wing locking mechanism.

Features

Moisture-Proof Nylon Body - Specialized water-resistant PA6 nylon compound prevents moisture absorption and swelling in bathroom environments, maintaining structural integrity where metal anchors would rust and fail.

Corrosion-Free Wing Design - 100% plastic construction ensures the four expanding wings never corrode, making this anchor permanently reliable in damp areas like bathrooms, laundry rooms, and outdoor covered spaces.

Hollow Wall Cavity Lock - The knot-expansion mechanism grips the inner face of plasterboard cavities securely, distributing load across a wide bearing area for stable towel hook and accessory mounting.

Flush Surface Finish - The anchor collar sits flush against the plasterboard surface after installation, creating a clean, professional appearance for visible bathroom fixture mounting points.
