M4 Knurled Reduced Head Low Profile Rivet Nut
The M4 Knurled Reduced Head Low Profile Rivet Nut is an internally threaded fastener designed for use in confined spaces, offering excellent anti-rotation performance and minimal surface protrusion. Its small-diameter flat head allows for nearly flush installation, making it ideal for applications that require a concealed finish or where aesthetics and space constraints are critical. The knurled body enhances grip with the base material, ensuring secure fastening even in high-vibration or soft material environments.

Automotive Interiors and Trim Panels
Enables concealed fastening in tight spaces such as dashboards, consoles, and door panels, while resisting vibration-induced loosening.Consumer Electronics and Device Housings
Ideal for slim enclosures where internal threading is needed without affecting surface profile or device integrity.Sheet Metal Fabrication
Provides a secure, flush-mounted threaded solution in thin-gauge metals where a low profile is required for clearance or aesthetics.Telecom and Control Enclosures
Used in rack-mounted or wall-mounted units where space-saving threaded inserts improve access and maintain enclosure dimensions.Medical and Laboratory Equipment
Supports clean, low-profile connections in precision assemblies, where both mechanical strength and visual design are important.Appliance Manufacturing
Ensures internal fastening in compact housing designs for kitchen, HVAC, and smart appliances, without interfering with exterior surfaces.
1. What is a reduced head low profile rivet nut?
It is a rivet nut with a smaller-diameter flat head that sits nearly flush with the surface, ideal for applications requiring minimal protrusion or concealed fastening.
2. Why is the knurled body important?
The knurled body increases surface friction within the parent material, improving resistance to rotation during installation and service, especially in softer or vibratory environments.
3. What are typical material options?
- Zinc-plated carbon steel (for general-purpose use)
- Stainless steel (304/316 for corrosion resistance)
- Aluminum (for lightweight, non-corrosive applications)
4. What applications is this type best suited for?
Used in automotive trim, electronics housings, sheet metal, appliances, and any setting requiring a flush, spin-resistant threaded insert in tight spaces.
5. What grip range is supported?
Standard grip range typically spans 0.5 mm to 2.5 mm, depending on the exact product specification.
6. How does this differ from a standard flat head rivet nut?
The reduced head is smaller in diameter, providing a lower visual and physical profile—ideal when clearance or appearance is critical.
7. What are the packaging and supply options?
Usually supplied in bulk cartons (1,000–5,000 pcs).
MOQ: 50,000
Custom packaging and OEM labeling can be arranged for volume orders.
