The Ceiling Overhead Winged Nylon Expansion Anchor is specifically engineered for upward overhead installation into concrete ceilings. The anchor features an enhanced collar grip ring and a slightly flared wing profile that provides immediate passive retention in the drill hole after hammer insertion, preventing the anchor from dropping out before the screw can be driven in.
The side wing deploys when the screw is driven upward, forming a barb lock in the concrete ceiling substrate that resists both gravity pull and vibration from ceiling-mounted equipment such as light fixtures, ceiling fans, smoke detectors, and HVAC diffusers. The pre-alignment collar accepts 2-3 pre-turns of the screw for single-unit overhead handling.
Molded from high-toughness nylon PA6, the anchor remains permanently rust-free with acid and alkali resistance for reliable performance in ceiling environments. The collar design includes a slightly enlarged flange that prevents over-insertion into the ceiling hole, ensuring consistent embedment depth across multiple mounting points.
Features
Anti-Drop Passive Retention: Enhanced collar grip ring and flared wing profile provide immediate passive friction retention in the drill hole after hammer insertion, preventing the anchor from dropping out before screw driving.
Gravity-Compensating Wing Lock: Side barb deploys upward into the concrete ceiling substrate, creating a mechanical lock that resists both gravity pull and vibration from ceiling-mounted equipment.
Smooth Tapered Nose: Precision-molded conical front tip guides the anchor smoothly into the drilled hole during hammer insertion, reducing insertion resistance and preventing body splitting or flaring at the collar.
Pre-Screw Alignment Collar: The anchor collar is designed to accept 2-3 turns of the screw before insertion, allowing the installer to pre-align the screw and anchor as a single unit for faster, more accurate placement.
Overhead Pre-Assembly Ready: Screw-and-anchor can be pre-assembled as a single unit at waist level before reaching overhead, eliminating the difficulty of aligning loose components above head height.
