When to choose STRUX SM™ studs?

STRUX SM™ is a high-performance self-clinching stud designed to be staked in a pre-punched hole on soft metal such as alloy, aluminum and copper. It offers a stronger and more reliable assembly alternative to traditional clinch and weld studs.

We recommend STRUX SM™ stud in the following situations:

  • Applications that require consistent push-out and torsional resistance.
  • Where welding dissimilar material is difficult or not possible.

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 stress-distributing ribs 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.
