Products

A blind rivet nut (also known as a rivnut, threaded insert, or blind nut) is a one-piece, internally threaded fastener designed to be installed from one side of a workpiece. It provides strong, permanent, and reusable threads in materials where traditional threading or welding is impractical—such as thin sheet metal, aluminum extrusions, plastics, fiberglass, and composites.

At Malaxy Fasteners, a leading fastening solutions provider with deep expertise in the global fastener industry, our rivet nuts are manufactured to international standards (ISO 15977, DIN 73378, IFI-146/147), ensuring consistent dimensional accuracy, reliable mechanical performance, and full compatibility with standard installation tools.

Malaxy is a recognized leader in the fastener industry, trusted by OEMs and distributors worldwide.

Key Features & Benefits

• One‑sided installation — Install from one side of the workpiece; no need to access the opposite side.

• Creates strong threads in thin materials — Ideal for sheet metal (0.5 mm – 6.0 mm), plastics, and composites.

• Replaces weld nuts — Eliminates weld splatter, toxic fumes, and sheet distortion; significantly safer and cleaner than welding.

• Multiple materials — Available in carbon steel, stainless steel (A2‑70 / A4‑80), and lightweight aluminum.

• Head styles available — Flat head, countersunk head, and large flange head for different assembly requirements.

• Body configurations — Round body (standard), knurled body (enhanced anti‑rotation), and full‑hex / half‑hex body (maximum torque resistance).

• Open end vs. closed end — Open‑end design for general‑purpose applications; closed‑end design for sealed, watertight, and dust‑proof installations.

Installation Tools

Malaxy rivet nuts are compatible with all standard installation equipment [13†L16-L19]:

• Manual hand tools — Ideal for prototyping, maintenance, repair, and low‑volume production (affordable, portable, no power source required)

• Pneumatic rivet nut guns — Consistent force output, best for high‑volume industrial production (automotive, aerospace assembly lines)

• Electric / cordless rivet nut tools — Balanced efficiency for medium‑volume manufacturing and on‑site installations

Proper installation requires the correct drill hole size. Always refer to the recommended hole size chart above and conduct test installations to verify grip and torque values for your specific material thickness.

Quality Assurance & Testing

All Malaxy rivet nuts undergo rigorous mechanical testing in accordance with international standards (ISO 14589, DIN 267‑30) [11†L31-L39]:

• Pull‑out testing — Measures axial force required to extract the rivet nut from the base material

• Spin‑out testing — Assesses torque resistance to prevent rotation within the installed position

• Thread fit testing — Go/No‑Go gauge verification to ensure thread accuracy

• Salt spray testing (ISO 9227 / ASTM B117) — For corrosion‑resistant finishes
