High performance self-clinching studs for soft metal 

When to choose STRUX SM™ studs?

How STRUX SM™ studs work?

STRUX SM™ studs can be installed manually in-die or automatically with hydraulic staking presses or any equipment capable of feeding weld studs or conventional clinch studs.

For optimum performance, STRUX SM™ studs must be fully installed with no “gap” between stud and engaged material.

  1. The stud end is fed through a punched or drilled hole and into a lower die.
  2. A punch applies force to the stud and retaining ring passes through the pilot hole. As pressure is applied, the displacement lobes are seated, forcing the engaged material into the retaining groove.
  3. Materials is displaced into the retaining groove. Stud is firmly locked into place.

STRUX SM™ studs benefits

  • High push-out and rotation resistance during service. Exceptional torque-out performance in soft metals.
  • Eliminates welding operations:
    • No material damage due to excessive heat.
    • Reduces the potential risk of corrosion.
    • Improves the aesthetics of the end-product.
  • Minimized panel distortion. It allows STRUX SM™ stud to be installed closer together or closer to panel edge.
  • Head diameter sized to prevent embedment of the stud into the application material.
  • Fast and easy installation, adapted both to automatic feed and in-die installation.
  • Cost saving opportunities:
    • Eliminates the cost of additional components, as sealants to prevent leakage (or other elements required in the installation of alternative products).
    • Eliminates production bottlenecks.
    • Longer life of installation tooling when comparing to similar products.
