91-Piece Petal Jack Nut Tool Kit – M4/M5/M6 Hollow Wall Metal Anchors with Installation Pliers for Drywall & DIY Repair
When There's Nothing Solid Behind the Wall, Give the Screw Something to Hold Onto.
A screw can feel tight at first and still pull straight out when the wall behind it is hollow. Petal jack nuts solve a different problem: once installed, the metal body expands behind the panel to create a wider mechanical anchor instead of relying on the front surface alone.
The Screw Isn't Always the Problem. Sometimes There's Nothing Behind It to Grip.
Hollow panels, thin sheet material and drywall-style surfaces don't behave like solid wood. A regular screw may bite initially, then loosen, spin or pull through because there isn't enough solid material around the threads.
Thin material may not provide enough thread engagement for a conventional screw.
Concentrating force around one small hole can allow a weak mounting point to deform or loosen.
The mounting location you need doesn't always line up with a solid backing point.
Squeeze the Tool and the Metal Body Opens Into a Wider Backside Anchor.
The slotted metal body is designed to deform outward during installation. As the anchor is compressed, the sections flare behind the panel, creating a broader bearing area than the original drilled opening.
Place the correctly sized petal jack nut into the prepared opening.
The included installation tool draws the anchor body into its expanded shape.
The expanded sections create a wider contact area behind the mounting surface.
Three Useful Sizes. Thirty of Each. One Installation Tool.
Instead of buying one anchor size and hoping every project matches, the kit includes M4, M5 and M6 options, giving you three fastening sizes ready for different compatible jobs.
90 anchor assemblies plus 1 installation plier.
Smaller-size petal jack nut assemblies.
Mid-size option for compatible installations.
Larger threaded option included in the assortment.
The Installation Pliers Are Already in the Box.
Petal jack nuts need to be compressed so the body expands behind the panel. The included hand plier gives you a dedicated installation tool rather than leaving you to improvise the setting process.
Designed to help compress compatible petal jack nuts during installation.
The plier-style design provides direct manual control during the setting process.
Anchors and the matching installation concept come together in one set.
The Expanded Shape Spreads Contact Across More of the Backside Surface.
Once set, the anchor body opens behind the panel. That expanded geometry helps distribute fastening force over a larger area than a bare screw relying only on the front-side hole.
Slotted metal sections flare outward behind the panel.
Expansion creates more backside surface contact around the mounting point.
The installed anchor provides a threaded fastening point for the compatible screw.
Carbon-Steel Construction Gives the Anchor a Rigid Expansion Body.
The fasteners are described as carbon-steel hardware with a zinc-plated finish, combining a rigid metal structure with a protective surface treatment suited to general fastening and maintenance use.
Metal construction provides the structure needed for the anchor to deform into its expanded shape.
The plated surface helps protect the metal during normal hardware use.
Keep several sizes available for repair, installation and maintenance projects.
Useful Anywhere a Conventional Screw Doesn't Have Enough Material to Bite Into.
Petal jack nuts are suited to compatible hollow-wall and thin-panel applications where access behind the surface is limited and a backside-expanding anchor provides a more practical fastening method.
Designed for installations where the fastener needs support behind a hollow surface.
Useful when the material thickness alone does not provide much thread engagement.
Keep the assortment ready for compatible household mounting and repair tasks.
Three sizes give hobbyists more fastening options from one kit.
Insert It. Set It. Expand It. Fasten Into It.
Use a correctly sized opening suitable for the selected M4, M5 or M6 anchor.
Place the petal jack nut through the panel until the flange sits at the surface.
Use the installation tool to compress the anchor and form the backside expansion.
Use the matching threaded fastener for the compatible mounting application.
M4, M5 and M6 Cover Three Common Small Fastening Sizes.
The assortment gives you three threaded options in the same 25 mm listed length, making it easier to keep multiple compatible sizes on hand for future projects.

Stop Treating Hollow Material Like It's a Solid Block of Wood.
- Limited material around the screw threads
- Fastener may spin if the hole becomes enlarged
- Pulling force stays concentrated near the opening
- Difficult when no solid backing is available
- Repeated tightening can damage a weak mounting hole
- Metal body passes through the prepared opening
- Anchor expands behind the panel
- Wider backside contact area after setting
- Creates a threaded mounting point
- Installation plier is already included in the kit
Ninety Anchors Mean the Kit Stays Useful After the First Project.
A small repair pack solves today's problem. A 90-anchor assortment gives you hardware left over for the next compatible project, the next room and the next mounting job that shows up later.
Enough quantity for multiple compatible fastening projects.
Keep M4, M5 and M6 available in one set.
The dedicated plier remains ready for the next installation.
Everything to Know Before You Squeeze the First Anchor.
The kit contains 91 total pieces: 90 petal jack nut assemblies plus one installation plier.
The assortment includes 30 M4 × 25 mm, 30 M5 × 25 mm and 30 M6 × 25 mm petal jack nut assemblies.
During installation, the slotted metal body is compressed so sections expand behind the panel, creating a wider backside anchor.
Yes. The set includes one hand-operated installation plier for setting compatible anchors in the kit.
They are intended for compatible hollow-wall and thin-panel applications. Suitability depends on material thickness, hole size, anchor size and the load being mounted.
No. Different anchor sizes require an appropriately sized mounting hole. Match the hole to the selected anchor before installation.
No universal load capacity should be assumed. Holding performance depends on the wall or panel material, thickness, installation quality, anchor size and the type of load.
Use the anchor only where its size, substrate and expected load are appropriate. For heavy, overhead or safety-critical installations, follow applicable hardware and structural mounting requirements.
