Blue Threadlocker 36ml Bottle

The Blue Threadlocker 36ml Bottle by PERMATEX is an essential maintenance product for law enforcement, military, and tactical professionals who demand reliability from their equipment. Threadlocking compounds prevent fasteners from loosening due to vibration, temperature cycling, and operational stress—critical concerns for firearms, optics mounts, rail systems, and tactical gear.

This medium-strength formula is designed for general-purpose locking applications across a wide range of fastener sizes and materials commonly encountered in field operations and equipment maintenance. PERMATEX Blue Threadlocker is an anaerobic adhesive that cures in the absence of air when applied between fastener threads, creating a strong lock while still allowing for disassembly with standard hand tools if future service becomes necessary.

Operators working with AR-15 platforms, pistol-mounted accessories, scope rings, and modular tactical systems benefit most from this threadlocker, as these systems experience continuous movement and stress. The 36ml bottle size provides adequate coverage for multiple applications, remaining serviceable in tactical environments where space and weight are premium considerations.
