General Information

The following sections contain general information about the product.


The Oval-Loc® clinching process is very similar to Tog-L-Loc® clinch joining. Each Oval-Loc® clinch joint is typically created in less than a second and features three basic steps as shown in this cross section diagram:

Tog-L-Loc Joining Steps An animation of the Tog-L-Loc clinching process

  • Step 1 (Clamps): A punch side stripper clamps the metals to be joined.
  • Step 2 (Draws): Next, a punch draws the metals into a die.
  • Step 3 (Locks): The Oval-Loc® die has moving blades which expand, allowing the metals to flow into a strong circular interlock.

The end result is a vibration resistant, leakproof clinch joint created without the use of expensive external fasteners or heat to cause distortion or warping of the part.
