Dykem Cross Check Tamper Proof Torque Marker

I use this on my ultralight aircraft engine and frame fasteners. It adds to visual check assurance and particularly speeds up preflight checks. Excellent material and very functional for its purpose, just needs a full 12hrs to cure. Does not come off on its own (vibrations, etc) but if you need it off during maintenance, just pick at it with a small flat pick/screw driver.

This product is a bit more expensive than comparable similar torque seals but it is great quality.

Bright and as easy to use as it is easy to see.

Works like a charm! Will be using it on a lot of things I work on.

Arrived quick and in good shape.
