Product description

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

The sealing clinch nut standoff uses a special structural design; after clinching into sheet metal, the rear side forms a blind hole that does not go through, which helps improve protection and sealing performance while providing a reliable internal thread connection point. It is suitable for enclosure-type structures that need sealed threaded connections in thin sheets but cannot tolerate welding distortion.

Technical Features
Clinch fastening plus a non-through blind hole structure on the back helps improve the protection ratingProvides a secure internal thread point in thin sheetsNo welding, avoids heat distortion and coating damageHigh torsion and push-out resistanceStainless steel / carbon steel optional, adapting to different corrosion protection levels
Applications
Telecom and server chassisNEV battery enclosuresOutdoor equipment enclosuresFloor scrubbers and cleaning equipment

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 sealed clinch standoff (Anti-Loosening) 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 surface treatments are available for the sealed clinch standoff (Anti-Loosening)? 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.

Q3In which applications is the sealed clinch standoff (Anti-Loosening) used?

Typical applications listed in the product description on this page: telecom and server chassis; new energy battery housings; outdoor equipment enclosures; floor scrubbers and cleaning equipment. Overview: the sealing clinch nut standoff uses a special structural design; after clinching into sheet metal, the rear side forms a blind hole that does not go through, which helps improve protection and sealing performance while providing a reliable internal thread connection point.

Q4What are the main features of the sealed clinch standoff (Anti-Loosening)?

Features listed in the product description on this page: clinch fixing with a non-through blind hole on the rear side, helping improve the protection rating; provides a stable internal thread connection point for thin sheets; no welding, avoiding thermal distortion of the sheet and coating damage; high torsional and push-out resistance.

Q5How should the sealing element material be chosen for the sealed clinch standoff (Anti-Loosening)?

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. (Applies to this model “Sealing clinch nut standoff (sealing series)”.)
