Pierce-clinch nuts
PIAS^® / RIVTEX^®

The cost-optimised alternative to weld nuts.

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
