Vibra-tite Premium Blue - สารกันคลายเกลียวชนิดกลาง

The blue tint makes application easy to see on small screws, and it’s held my optic plate bolts firm through two range trips without a hint of backing out. A tiny drop on the threads does the job, and the cap stays clean so it’s ready for the next project.

Took my holster screws out after a few hundred rounds and they were still torqued down tight, which never happened before. A single drop on each thread and I didn’t have to touch them again.

The applicator tip is precise enough to get a small drop right on the screw threads without making a mess. My holster screws haven't budged through a few hundred rounds at the range, which is exactly what I needed.
