Product description

Compiled from the existing technical description of this product on this site

The Type 71 flat-head knurled sealing rivet nut uses a flat-head knurled structure and is installed in sheet metal by riveting; after riveting, the head is flush with the panel surface, meeting high flatness requirements while providing waterproof sealing. It is suitable for thin-sheet structures where the visible surface must be flat and a sealed threaded connection is also required.

FAQ

Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.

Q1What material is the Type 71 flat-head knurled sealing rivet nut (knurled outer diameter, good torque resistance) made of? What strength level does it reach?

The specification table on this page states: material is carbon steel / stainless steel (optional). Material certificates and mechanical property test reports can be provided with the goods; batch acceptance follows the specifications above.

Q2What are the main features of the Type 71 flat-head knurled sealing rivet nut (knurled outer diameter, good torque resistance)?

Features listed in this product description: flat-head design sits flush with the panel surface after riveting for high flatness; knurled outer diameter for good torque resistance; sealing function to meet waterproof requirements; single-stroke riveting, no welding required, high efficiency.

Q3To which standard is the Type 71 flat-head knurled sealing rivet nut (knurled outer diameter, good torque resistance) produced and inspected?

Standards stated in the specification table on this page: rivet nuts refer to the GB/T 17880 series; Type 71 flat-head knurled structure per customer drawing / corporate standard; ingress protection IP68 (IEC 60529). Dimensional inspection reports can be provided with the goods; batch acceptance is carried out in accordance with the above standards and the drawings agreed by both parties.

Q4What surface treatments are available for the Type 71 flat-head knurled sealing rivet nut (knurled outer diameter, good torque resistance)? How to choose?

Surface treatment specified in the specification table on this page: zinc-plated / passivated (optional). Different coatings differ in appearance, corrosion resistance and cost; select according to the service environment and the order agreement.

Q5How should the sealing element material be chosen for the Type 71 flat-head knurled sealing rivet nut (knurled outer diameter, good torque resistance)?

Select according to the sealing medium, temperature and compression set requirements: nitrile rubber (NBR) is common for mineral oils, fluororubber (FKM) withstands high temperatures and chemical media, and silicone rubber offers good elasticity at low temperatures. O-ring sizes are selected per the GB/T 3452.1 series; avoid scratching and excessive stretching during assembly.
