How to Adjust Snap-Lock Profile Tightness

Machine service & troubleshooting
Rick Zand|January 4, 2024

Snap-lock profile tightness may occasionally need adjustment. In this step-by-step guide, you will learn the process of making snap-lock profile adjustments to achieve your desired tightness.

At New Tech Machinery (NTM), we’ve helped metal contractors by providing the highest quality portable rollforming machines and machine support. We feel it’s important to educate our machine owners on how to operate their machines to their full potential. This includes showing you how to make adjustments to the machine and tooling when necessary.

For this adjustment, you’ll need the following tools:

  • 5/32 Allen wrench
  • Small pair of pliers
Tightness check on snap-lock panels

Step 1: Examine the Snap-Lock Profile

Before making any adjustments, it’s essential to examine the snap-lock profile to determine whether it needs to be tighter or looser. Test how your panel snaps together to gauge its current tightness.

Step 2: Locate the Set Screw

On all snap-lock profiles, you will find a set screw associated with a shaft. This set screw is typically located at station 13R, on the right side of the machine, station number 13. You’ll see the shaft connected to it.

Step 3: Loosen the Set Screw

Insert your 5/32 Allen wrench into the set screw hole and gently loosen it. Be sure to loosen it enough to allow for adjustment.

Step 4: Adjusting Tightness

Depending on whether you want a tighter or looser snap, use the following steps:

For a Tighter Snap:

Counterclockwise for a tighter snap

On certain profiles, you may need to use a small pair of pliers on the shaft.

Rotate the shaft counterclockwise, which will tighten up the snap.

This action pinches the side of the panel shut and brings the roller underneath closer.

Clockwise for a looser snap.

For a Looser Snap:

Rotate the shaft clockwise, moving it away from the side of the panel. This will create a looser snap.

Step 5: Secure the Set Screw

Once you have made your desired adjustment, tighten the set screw securely using your Allen wrench.

Step 6: Mark the Adjustment

It’s a good practice to mark the panel where you made the adjustment. This will help you identify the location of the change when you’re ready to work with the panel further.

Step 7: Cut the Panel

Run panel past the mark
Run the panel past the mark. (NEVER REACH THROUGH THE SHEAR. Always work behind or in front of it.)

Now, run the panel out past your marked adjustment point and cut it off. This ensures that the adjustment point won’t be visible in the final product.

Step 8: Test Your Desired Snap

After making the adjustment, test your panel to ensure that it now has the snap tightness you desire. If it’s still not where you want it, you can repeat the adjustment process.

Step 9: Final Checks

Once your snap-lock profile is adjusted to your liking, you can choose to do one of two things:

  • If it needs to be tighter, make further adjustments following the same process.
  • If it needs to be looser, repeat the adjustment steps.
