🔩 Zinc Plated Steel Rivnuts – Threaded Nutserts Knurled Rivet Nuts M3 to M10 | Blind Installation
🏷️ Brand: HomeDIYer Fastener | Large Flange | Knurled Body | BZP | Metric Coarse
📌 Overview — Add strong, permanent threads to thin or hollow materials. Need a threaded hole in sheet metal, plastic, or tubing where you can't reach the back side? Our Zinc Plated Steel Rivnuts (Threaded Nutserts) are the answer. These blind rivet nuts install from one side, creating a durable, reusable female thread in materials as thin as 0.5mm. The large flange distributes load and prevents pull-through, while the knurled body grips the parent material to resist rotation. Perfect for automotive panels, electronics enclosures, furniture assembly, and any application where traditional nuts or tapping aren't feasible. Zinc-plated for moderate corrosion resistance. Available in metric sizes M3 to M10. Choose your exact quantity – ideal for fabricators, repair shops, and DIYers.
✨ Key Features – Knurled Rivet Nuts (Steel, BZP)
-
Blind Side Installation – Installs from one side of the workpiece – perfect for hollow sections, tubing, and panels with no rear access.
-
Large Flange Head – Wide flange distributes clamping load and prevents pull-through in soft or thin materials.
-
Knurled / Serrated Body – The body features grooves that bite into the parent material, preventing rotation when tightening bolts.
-
Zinc Plated Steel (BZP) – Bright zinc plating provides good corrosion resistance for indoor and light outdoor use.
-
Metric Coarse Threads M3–M10 – Standard ISO metric threads (M3x0.5, M4x0.7, M5x0.8, M6x1.0, M8x1.25, M10x1.5).
-
Reusable Threads – Creates permanent, high-quality threads that can be used repeatedly with standard bolts and screws.
-
Easy Installation – Use a standard rivet nut tool (hand or pneumatic) for quick, consistent setting.

💡 Installation & ordering: Use the recommended drill size to create the hole. Insert the rivet nut into the hole, then use a rivet nut setting tool to collapse the body, forming a bulge on the blind side. The knurled body prevents spinning. Packaging: “As per Your Choice” – order the exact thread size and quantity you need. Contact us for bulk or custom assortments.
🔧 Corrosion note: Bright zinc plating offers moderate rust protection – ideal for indoor applications, automotive interiors, and light outdoor use. For marine or high-humidity environments, consider stainless steel rivet nuts (sold separately).
❓ Frequently Asked Questions – Rivnuts / Threaded Nutserts
What is the advantage of a knurled body rivet nut?
🔧 The knurled (serrated) body grips the inside of the hole when the rivet nut is set, preventing the nut from rotating when you tighten a bolt into it. This is essential for applications where the nut will be subjected to torque or vibration.
What drill size should I use for each rivet nut?
📏 M3 → 5mm, M4 → 6mm, M5 → 7mm, M6 → 9mm, M8 → 11mm, M10 → 13mm. Using the correct drill size ensures proper setting and a tight fit.
Can I install these rivet nuts without a special tool?
⚙️ While possible with a bolt, nut, and washers (DIY method), we strongly recommend using a proper rivet nut setting tool (hand or pneumatic) for consistent, reliable results. Improper installation can lead to loose or spinning nuts.
What materials can I install these rivnuts into?
🔩 These rivet nuts work well in sheet metal (steel, aluminum), plastic, fiberglass, and composite panels. The minimum material thickness should be at least the flange thickness plus 0.5mm. For very soft materials (thin plastic), consider using a backup washer.
Will these rivet nuts rust? Are they suitable for outdoor use?
🌧️ The zinc plating provides good protection for indoor and light outdoor use. For prolonged outdoor exposure or coastal environments, the zinc may eventually corrode. For such applications, we recommend our stainless steel rivet nuts (A2 or A4).
