Vibra-Tite VC-3 Threadmate is one of the most versatile thread lockers available. An alternative to traditional liquid lockers, which cure to form a complex bond, VC-3 is a proprietary blend of thermoplastic elastomer resins designed to remain flexible and absorb vibration. The combination of inert/non-reactive amorphous resins creates a tough, semi-solid layer inside the threads of a mated joint. VC-3 damps the vibrational energy transferred between the threads of a mated fastener, preventing fastener loosening and loss of clamp load. These unique differences make VC-3 coated fasteners adjustable, removable, and reusable.
An acrylic polymer that damps and absorbs vibration
Will not harden like anaerobic thread lockers
Works with metal, wood, plastic (*see table), and more
Fasteners are easily adjusted, removed and reused
Works on fasteners of any shape or size, from tiny eyeglass screws to large construction bolts
Works with internal or external threads
Meets low out-gassing specifications (NASA SP-R-0022A, per ASTM E 595)
Parts coated with Vibra-Tite VC-3 can be stored indefinitely before use.
Versatile Adheres to ferrous and non-ferrous metals, most platings, wood, and plastic (see table) screws.
Versatile Adheres to ferrous and non-ferrous metals, most platings, wood, and plastic (see table) screws.
Multiple reuses Steady pressure and standard hand tools allow parts coated with VC-3 to be easily adjusted, removed, and reused.
Minimizes galling / stripping Since Vibra-Tite VC-3 remains a thick, resilient, viscous resin, its cold flow properties actually minimize the galling or stripping of soft threads during reuse.
Underwater installation Unlike anaerobic thread lockers, VC-3 can be air dried and installed into a mating part under fresh and salt water.
Shake well before each use. Apply VC-3, a length of 1 to 1 ½ times the fastener diameter, filling threads 30-50%. Although material will be dry to touch within minutes, allow VC-3 to dry for at least 30 minutes (the longer, the better), depending on part size. Fasteners are then ready for assembly or to be stored for later use.
From tiny eyeglass screws to huge construction bolts, Vibra-Tite VC-3 is ideal for fasteners of any size.
Mounting ski / snowboard bindings, plates and inserts.
RC models (Drones, Airplanes, Helicopters).
Bolts on motorcycles.

Reusability
Using steady pressure and standard hand tools, parts coated with Vibra-Tite VC-3 can easily be adjusted, removed, and reused up to 5 times.
Minimizes Galling/Stripping
Since Vibra-Tite VC-3 remains a thick, resilient, viscous resin, its cold flow properties minimize galling or stripping of soft threads during reuse.

Moderate
Breakaway torque
No distinct break; slow, fluid release as material cold flows
This is nearly identical to my first pilot logbook, but with a new smooth matte black cover. This logbook checks all the boxes from student pilot through Commercial. It might just be the only logbook you’ll ever need. Fly safe!
