V-Loc Sheet Metal Clinching System

BTM's standard for Clinching Aluminum, and is also ideal for when visibility requires a rivet look.

What is V-Loc?

V-Loc is a visually improved Tog-L-Loc® joint which features a raised spherical inner diameter with a concentric outer ring. This design is intended to give the appearance of a more traditional fastener, but the process is essentially the same as the trusted Tog-L-Loc® joining method, which clinches sheet metals together using a punch and a die rather than the application of external fasteners or welding.

V-Loc Features & Benefits

  • Joints are aesthetically pleasing, strong, vibration resistant, and leak-proof!
  • Ideal for use in a location which will be seen by discerning customers.
  • Stronger than Tog-L-Loc® when joining some aluminum alloys.
  • Environment friendly - no fumes or sparks.
  • Non-Destructive checking.

General Information

The following sections contain general information about the product.


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

V-Loc Joining Steps

  • 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 Tog-L-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 hinder the effect of coatings.

Originally developed to respond to a customer’s request for a nicer looking clinch joint button V-Loc also provides improved material flow within the clinch joint to increase its strength especially when joining certain aluminum alloys. A thicker side wall and improved interlock increase shear and peel strength by approximately 25% over Tog-L-Loc® when joining some aluminums as shown in the table below:
