How to use

Drill or prepare a correctly sized countersink hole in the sheet material to the dimensions matching the rivet nut geometry. Insert the blind rivet nut from the accessible side so that the countersunk head sits flush with the sheet surface. Use a suitable blind rivet nut tool or mandrel designed for M10 rivet nuts to set the nut: apply steady pulling force until the nut deforms and clamps to the sheet. After installation, verify the M10 thread by trial-fitting the appropriate fastener to ensure secure engagement.

Recommendations

For best results, confirm hole and countersink dimensions against the rivet nut geometry and use a torque-controlled fastener when assembling components to avoid overloading the installed thread. Select a blind rivet nut installation tool compatible with M10 sizes and follow the tool manufacturer’s safety and operating instructions.
