What Are Clip On Nuts?

Clip on nuts, also known as sheet metal nuts or self-clinching nuts, are fasteners designed to be securely attached to sheet metal or other thin materials without the need for welding or additional hardware. They feature a spring-loaded clip or prongs that grip the material when pressed into a pre-punched or drilled hole, providing a strong, threaded attachment point.

Materials

Clip on nuts are available in various materials, including:

• Carbon Steel (often zinc-plated for corrosion resistance)

• Stainless Steel (A2/AISI 304 or A4/AISI 316 for high corrosion resistance)

• Brass (for electrical conductivity and corrosion resistance)

• Aluminum (lightweight and corrosion-resistant)

Surface Treatments

Common surface treatments for clip-on nuts include:

• Zinc Plating (standard corrosion protection)

• Nickel Plating (enhanced wear and corrosion resistance)

• Passivation (for stainless steel to improve corrosion resistance)

• Black Oxide (for aesthetic and mild corrosion resistance)

Specifications

Clip on nuts come in various sizes and thread types, including:

• Thread Sizes: M3, M4, M5, M6, #6-32, #8-32, #10-24, 1/4″-20, etc.

• Material Thickness Range: Typically 0.5mm to 3mm

• Holding Style: Spring clips, prongs, or serrated edges

Applications

Clip on nuts are widely used in industries where sheet metal assembly is common, such as:

• Electronics & Electrical Enclosures

• Automotive Panels & Trim

• HVAC Systems

• Furniture & Cabinetry

• Industrial Machinery & Equipment

Excellent Case: Automotive Panel Assembly

Scenario: A car manufacturer needs to secure interior trim panels without welding to avoid damaging the paint or underlying structure.

Solution: Clip-on nuts (M5 stainless steel, zinc-plated) are pressed into pre-drilled holes in the sheet metal. The trim panel is then bolted securely without requiring additional nuts on the backside, speeding up assembly and reducing labor costs.

Benefits:
✔ No welding required – prevents heat distortion
✔ Quick installation – reduces assembly time
✔ Secure hold – resistant to vibration and loosening
✔ Corrosion-resistant – ideal for automotive environments

This application demonstrates how clip-on nuts provide an efficient, reliable fastening solution in high-volume manufacturing.
