High-Strength Red Threadlocker for Demanding

Vibra-TITE 21305 VC-3 is a high-strength acrylic threadlocker supplied in a 0.16 fl oz tube. It secures fasteners up to 1 1/2 inches in diameter on non-ferrous metals, plastics, plating, and wood. The red color identifies its permanent-grade holding power for critical joints.

Non-Hardening Formula Allows Repeated Disassembly

Unlike conventional anaerobic adhesives, this compound cures to a non-hardening state that retains breakaway torque without locking threads solid. A working time of one minute lets you position parts before the bond develops. The material supports up to five reuse cycles on the same hardware without reapplication.

Acrylic Base Withstands 165 °F in Service

The acrylic chemistry operates reliably to a maximum temperature of 165 degrees Fahrenheit and offers a flash point of -39 degrees Fahrenheit. Viscosity is capped at 300 cps for controlled flow into fine threads. NASA SP-R-0022A qualification confirms suitability for aerospace and high-reliability maintenance programs.

Questions about this item

Does the VC-3 threadlocker generate heat or require power when left on a fastener all day?

The acrylic-based VC-3 is a non-hardening liquid that cures without heat or electricity, so it adds no thermal load or power draw to the assembly.

What materials must the fastener and mating part be made of for this red VC-3 to work?

The product is rated for non-ferrous metal, plastic, plating and wood substrates with threads up to 1 1/2 in diameter.

Will the cured VC-3 damage older plated or non-ferrous hardware if I need to disassemble it later?

The non-hardening cure and five-reuse rating let you break away and reapply on the same plated or non-ferrous threads without degrading the original surfaces.
