Lance-N-Loc® Sheet Metal Clinching System

A strong, rotation-resistant clinching method for joining harder materials or multiple layers of sheet metal.

What is Lance-N-Loc®?

Lance-N-Loc® is a sheet metal clinching system which creates a strong mechanical joint by lancing the 2 long sides of the joint and gradually drawing the ends. The material on the sides of the joint is compressed and interlocked, while the gradually sloping ends allow harder materials to be joined making higher strength joints, all in a single press stroke.


Note: Lance-N-Loc® is not leak-proof.
See Oval-Loc® for a rotation-resistant leak-proof clinch joint.

  • Lance-N-Loc® is a cold-forming clinching process. It does not use fasteners or welding.
  • Ideal for harder metals, or multiple layers of metals.
  • Maintains electrical conductivity.
  • Part of BTM's Geo-Clinch® Line of Clinching Joints - Ideal for Geo-Set Applications!

General Information

The following sections contain general information about the product.


The Lance-N-Loc® process takes place in a single press stroke:

  • Step 1: The first step in the process involves the clamping of the material with a punch side stripper.
  • Step 2: Next, the punch draws the material into the die.
  • Step 3: As the material flows into the die, the die blades expand, allowing the metal to flow into a strong interlock below the bottom sheet.

BTM has a long history of designing and building both standard and special equipment to help you successfully implement cost saving clinching solutions. From standard punch & die tooling to complex multi-process automated systems, BTM can design and build a solution that is right for you.
