The M6 x 40mm Nylon Four-Wing Knot Expansion Wall Plug is a wide-load plastic fastening solution designed for wall shelves, bookcases, and storage brackets on aerated concrete and lightweight block surfaces. The anchor features a four-wing knot-expansion body made from premium PA6 nylon that deploys across an extra-wide 22mm bearing area behind the wall surface, distributing shelf loads safely across the porous aerated substrate. The pull-out resistant design ensures shelves remain securely anchored even under the weight of books and stored items. Installation requires drilling a 10mm hole at the marked position, inserting the anchor until the collar is flush with the wall, and driving the M6 screw to expand the four wings into a secure knot-lock behind the aerated concrete face.
Features
Hollow Wall Cavity Fixing - Purpose-built for hollow and aerated substrates, the knot-expansion wings engage deep within the cavity space, creating a secure anchor point even in porous and crumbly aerated concrete blocks.
Wide Load Distribution - The four-wing design expands to a full 22mm diameter behind the wall, spreading shelf loads across a generous bearing area to prevent localized crushing of the aerated concrete substrate.
Pull-Out Resistant Design - The knot-lock mechanism resists forward pull-out forces typical of cantilevered shelf loading, maintaining secure wall engagement even under the sustained weight of books and decorative items.
Reinforced Wing Hinges - Thickened hinge points where wings meet the anchor body resist fatigue failure during repeated shelf loading and unloading, ensuring long-term structural reliability in storage applications.
