Professional Petal Nuts Expansion Screws & Jack Nuts
The ultimate heavy-duty hollow wall anchor. Expands into a secure "petal" formation behind drywall, wood, or thin metal to lock fixtures firmly in place without collapsing.
Why DIYers Prefer Our Petal Expansion Nuts
🌸 Unique Petal Expansion Design
As the screw is tightened, the anchor body splits and folds outward into sturdy "petals," locking tightly against the back of hollow walls for superior load-bearing strength.
🛡️ Heavy-Duty Load Capacity
Engineered to securely hold heavy items such as wall cabinets, shelves, light fixtures, mirrors, and brackets on hollow or thin materials where standard screws fail.
⚙️ Premium Zinc-Plated Steel
Crafted from high-strength carbon steel with a corrosion-resistant zinc plating, ensuring long-lasting durability, rust prevention, and maximum structural integrity.
🔧 Easy & Quick Installation
No specialized setting tools required! Simply drill the correct hole size, insert the anchor, and tighten with a standard screwdriver or drill bit.
📋 Versatile Hollow Wall Applications
Perfect for drywall, gypsum board, wood paneling, hollow core doors, plastic boards, and thin sheet metal casings.

Verified Customer Reviews
David R. (Columbus, OH)
"Standard plastic drywall anchors always pull out when hanging heavier shelves. These petal nuts grip the backside of the drywall like a vice! Extremely solid and secure."
Kevin M. (Phoenix, AZ)
"Used these on a hollow core door to mount a heavy organizer rack. They expanded perfectly and held firm without crushing the material. Great engineering!"
Jason L. (Atlanta, GA)
"High-quality steel and clean threads. Installation was straightforward with a standard screwdriver. Highly recommend for any home remodeling project."
Frequently Asked Questions
What surfaces are best suited for these expansion screws?
They are specifically designed for hollow walls, drywall, wood panels, hollow doors, plastic sheets, and thin metal plates where traditional screws cannot get a secure grip.
Do I need a special installation tool?
No special tool is required. A standard manual screwdriver or power drill set to low torque is all you need to expand and lock the anchor in place.
Will these anchors damage or crack drywall?
No. The petal expansion distributes pressure evenly across the back of the wall material, preventing crushing or cracking compared to tapered wedge anchors.
Are these screws rust-resistant?
Yes, they are coated with a heavy-duty zinc plating that protects against corrosion and rust, ensuring long-term durability indoors.
