Rivet nut Rapid Tools 5000670 M3 steel chrome, pack of 20

Rapid Tools 5000670 M3 rivet nuts are steel, chrome‑finished threaded inserts supplied in a pack of 20. They are designed to form durable internal M3 threads in thin sheet materials where conventional tapping is impractical. These rivet nuts are intended for use with manual or pneumatic rivet nut tools and provide a reliable way to mount panels, enclosures, brackets and other components to sheet metal, composite panels or tubing.

Advantages

The steel construction with a chrome finish ensures good strength and corrosion resistance in many indoor applications. Supplied in a pack of 20, these M3 rivet nuts offer consistent thread quality for repeated assembly and repair tasks. Their design allows installation from one side of the workpiece, creating a load‑bearing internal thread without access to the opposite side. Compatible with standard M3 fasteners, they simplify mounting thin materials and improve joint reliability compared with self‑tapping screws.

Suitable for

• Creating M3 internal threads in thin sheet metal (0.5–1.5 mm thickness range)
• Assembly and repair of enclosures, control panels and equipment housings
• Mounting brackets, panels and fixtures to metal or composite substrates
• Applications where access is available only from one side of the workpiece

When it may not be suitable

These rivet nuts are intended for thin materials; they are not appropriate for thick structural components or where a welded or insert nut with higher shear capacity is required. The chrome finish provides basic corrosion resistance suitable for many indoor environments but may not be adequate for continuous outdoor exposure or aggressive chemical environments without additional protective measures.

Key specifications

• Thread size: M3 internal thread
• Material: steel with chrome finish
• Recommended grip/thickness range: approximately 0.5–1.5 mm
• Quantity per pack: 20 pieces

How to use

Select a rivet nut tool compatible with M3 rivet nuts and set the correct mandrel and nosepiece. Drill a correctly sized hole in the workpiece according to the rivet nut manufacturer’s recommendations. Insert the rivet nut from the accessible side, place the tool onto the nut, and actuate the tool to deform the unthreaded shank and form a secure clinch against the sheet. Confirm the rivet nut is fully seated and that the internal thread accepts an M3 screw or bolt without excessive play.

What to consider before purchase

• Verify the sheet thickness to ensure it falls within the rivet nut’s grip range (about 0.5–1.5 mm).
• Ensure you have a compatible rivet nut tool and correct mandrel/nosepiece for M3 size.
• Consider the environment and whether the chrome finish provides sufficient corrosion protection for your application.
• Confirm that M3 thread strength and shear capacity meet the load requirements of the assembled parts.

Usage recommendations

Use the rivet nuts with a calibrated rivet nut tool and appropriate hole size to achieve consistent installation. For outdoor or corrosive environments, consider additional surface treatment or selecting stainless steel inserts. Check thread engagement with the intended fastener and avoid overtightening M3 screws to prevent thread damage.
