Clinching nut - Import export

With PIAS® pierce-clinch nuts (square) and RIVTEX® (ROUND) a non-detachable metal fastening can be created at optimum cost. The pierce-clinching technology is suitable for steel and aluminium sheets, causes very little cost for inspection and control, and allows several pierce-clinch screws to be processed in a single stroke. PIAS® and RIVTEX® pierce-clinch nuts offer the following advantages over welded nuts: corrosion-resistant no weld spatter on the thread no thermal weakening at the fastening position self-piercing higher torque requirements high process reliability in fully-automated processing flush-mounted processing processing can be manual, semi or fully automated self-locking thread possible

How the fastener functions The material is peeled and a collar formed so that a flush and positive fit of the fastener is created with the sheet metal material. This can either transfer very high forces (e.g. AX 20x14) or with the version that is flush with the sheet, the fastener can be used to directly mount connected parts (e.g. AX 16x4). This principle can be applied to almost every material. The benefits of the RIVORM® HR clinch nut one nut for all sheet metals up to 4.5 mm cost-saving due to fewer variants high-strength, press-hardened and hot-stamped steels very good torsional strength regardless of metal strength high pull-out force The benefits of the RIVORM® TR rivet for fitting ties and springs fully automated processing possible in the subsequent composite tool can be applied universally for different assembly jobs, such as fastening electrical control units, or other plastic parts, simply by clipping them in

Manufacture by machining is battling against the rising cost of materials and long machining times. That's why many companies are finding our forming process for hollow parts of increasing interest. We have other forming options for machine-finishing in-house. Our cold-forming process is distinctive – including for thin-walled hollow parts because of: rolled (chip-free manufacture) external threads suitable surfaces for maximum corrosion requirements Some examples of Conform® hollow parts and nuts: sensor housing union nuts for hydraulic, brake and fuel lines clinch nuts
