Industry News: Sheet‑Metal Housing Lightweight Drives Growing Adoption of Clinch Nuts & Studs for Electric‑Control and Battery‑Pack Housings

Compared with welded nuts, clinch nuts and studs require no welding and keep flat surface. They are suitable for thin‑sheet processing and widely adopted in telecommunication cabinets, electric‑control housings and new‑energy battery‑pack assemblies. Demand for blind‑type clinch nuts rises significantly for waterproof sealed enclosures.

Application‑Scenario Features

General telecommunication cabinet: Adopt standard through‑hole clinch nuts. Match pilot‑hole dimension and sheet thickness for repeated disassembly‑assembly.

Waterproof sealed housing: Select blind clinch nuts with no through‑hole on reverse side for basic enclosure sealing performance.

New‑energy battery‑pack housing: Mostly thin aluminum sheet. Match fastener material with aluminum alloy and control press‑in pressure to prevent plate cracking.

Common Procurement Notes

• Sheet thickness must match clinch‑fastener specification; over‑size fastener on thin sheet easily causes plate cracking;
• Pilot hole shall comply with product standard. Oversized hole reduces pull‑out strength; undersized hole brings excessive press‑in resistance;
• Clearly specify blind‑hole requirement for sealed‑housing projects, avoid mis‑using ordinary through‑hole clinch nuts.

Driven by sheet‑metal lightweight trend, knurl‑forming quality and batch pull‑out‑force consistency become key supplier evaluation indicators.
