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

This torque seal is very easy to use, sticks quite well to a variety of metals, and is removable with a razor or pick. I used it on my motorcycles to monitor safety critical fasteners in high-vibration environments with wide temperature ranges, and the crosscheck stays on every time. Just make sure you clean the fasteners and areas with rubbing alcohol before applying, and let it dry for about a day before returning to use. Wear disposable gloves when handling, this stuff stains any clothing permanently.

Great purchase

Works good, only downside is it's like anti-seize, if you look at it wrong, it's all over everything, including you. I'd prefer it to be a little thicker consistency, and a smaller tip, it would make it easier to apply. Other than that, the color is clear, easy to see, and once it dries, its solid, so if there's any unwanted movement of the bolt/nut/whatever, you can clearly see it cracked or sometimes completely flaked off, which is exactly what it is supposed to do.

This is brand of torque seal is generally great quality. However the low rating is for the fact that I ordered 4 tubes in Red @$14.50 each but received Orange instead. I cannot use them. This seller’s restrictions do not allow refunds or exchanges. So I’m stuck with a product that is not in compliance with my company’s annual color code. I’m so disappointed. :-(

Since I could not leave a no star rating… had to leave a 1…. Received today, opened package and the tube is dried up, used a small thin nail to push into the tube and noting. Tried to start a return, un-returnable. Maybe this review will get someone’s attention…

Tube came with a puncture and dried. Color is pink not red. Otherwise I'm sure it's a good product
