DYKEM Cross Check Torque Seal Tamper-Proof Indicator ($8.22 each when ordering 25 or more)

Works as advertised great product

Easy to apply and will definitely indicate if something has moved. Be careful about the color choice. I picked blue so that it wouldn’t be too obvious on a black surface. I should have gone with a lighter color. The dried paint is rugged enough to stand up to vibration but it will crack to immediately show if something has moved.

worked like a charm

Súper thanks

I always have a tube of this on hand when working on my Jeep. It is a must have.

Good price. Easy transaction.

I go through two-three tubes of this stuff a day at work. I had no idea it was so pricey. Glad I'm not paying for it. Anyways, I work at a test center for one of the large vehicle manufacturers and we put this stuff on every single fastener after torquing them to spec so that we can check with a glance during out inspections that all the fasteners are still tight. It also doubles as a movement checker too. I've crossed gaps in body panels, where two brackets collide, and even put it on a tool box to see if someone was taking my tools when I wasn't around. Great stuff. Pricey, but great. I'll just be 'borrowing' it from work when I need it.

Well nothing has moved yet, it’s expensive for what it is hence the 3 stars. If it fails I’ll edit this.
