September 23, 2026Nicholas C.Verified BuyerThis simple thing just made my day!I don't know if anyone needs to know this but I searched high and low for a fix myself. Producers Pride sentinal coop where the roof has to be bolted into everything all 3 pieces of roof the rivets or jack nuts or what ever they are called were incorrectly put in and jacked up. ANY way I didn't want the hassle of taking it apart and fighting with tractor supply so I found parts that worked and was so easy to do. I bought this kit and it fits the number 26 on the parts list that are used for attaching all the roof pieces. the drill bit they sent was to long for piloting the hole to fit the new jack nuts but I just used a steel bit and shaved off the edges until it fit the jack nut. I spent 80 bucks until i found this kit to fix it!

September 20, 2026TheRealMindyC.Verified BuyerInstalling shelves in a vanWe got these screws to install some shelves in our Sprinter van and they are perfect for that. The only negative is that we would have needed a bigger drilling head for the installation but we hacked it and worked out in the end. It’s absolutely worth it as the similar screws without any additional items cost way much more in other places.

Frequently Asked Questions
How do petal nuts work?
Petal nuts are designed to create a solid, threaded mounting point from the front when you cannot access the back of a material. Using the included installation plier, the fastener's body expands evenly behind the surface into petal-like anchors, creating secure threads where a regular screw cannot grip.
What materials and applications are they suitable for?
They work on hollow walls, drywall, thin panels, and hollow metal. Common applications include automotive repairs, woodworking, bracket mounting, hanging hooks, and general home renovation projects.
What sizes and contents are included in the kit?
The kit includes 90 petal nuts across three sizes—M4, M5, and M6—measuring 25 mm, along with one dedicated manual installation plier.
What material are the petal nuts made of?
They are manufactured from high-strength carbon steel with a zinc-plated finish to provide durability and resist rust and corrosion.
Do I need access to the back of the panel to install them?
No. The system is built specifically for blind installations where rear access is blocked or unreachable, allowing you to complete the entire anchoring process purely from the front.
