How to feel safe in an unsafe world? Torque striping

We apply a colorful strip of thin lacquer to a bolted connection to indicate it has been torqued to the proper value giving the desired preload. Once cured, the stripe stays pliable under extreme temperatures and vibrations. If the stripe separates, you know the bolted connection has moved, reducing the preload—and it’s time for another tightening.

That’s because we offer torque striping on demand as an added safety feature. You’ll find torque striping on applications such as large tractor engines and mission aerospace equipment. Think of it like a wax seal of safety for industrial use.


We apply a colorful strip of thin lacquer to a bolt/nut to indicate it has been torqued to the proper value. Once cured, the stripe stays pliable under extreme temperatures and vibrations. If the stripe moves or separates, you know the bolt has come loose or been compromised in some way—and it’s time for another tightening.

That means no more wasted time checking bolt torques during inspection. Torque striping is a secure, visual indication that things are tight and right.
