Medium Threadlocker 10ml Bottle - Blue

The Medium Threadlocker 10ml Bottle - Blue by PERMATEX is a surface-insensitive anaerobic adhesive formulated for fastener assembly where moderate strength and controlled disassembly are required. This product is designed for technicians, mechanics, and assembly professionals who need reliable fastener locking on threads ranging from 1/4" to 3/4" in diameter. Whether securing bolts in machinery, firearms, automotive components, or tactical equipment, this medium-strength threadlocker provides dependable performance without requiring perfect surface preparation.

PERMATEX's blue threadlocker formula works through anaerobic polymerization, curing only in the absence of air and in the presence of metal ions—eliminating the need for surface cleaning or priming in most applications. The medium-strength rating allows fasteners to be disassembled with standard hand tools when maintenance or adjustment is necessary, distinguishing it from permanent red variants. The 10ml bottle delivers precision application through a controlled dispenser tip, ensuring consistent bead placement and minimal waste. This formulation resists vibration loosening, prevents leakage around threads, and maintains effectiveness across a wide temperature range typical of industrial and field environments.

Users benefit most from this threadlocker when assembling critical fasteners that may require future service—such as scope mounts, rail systems, action screws, and mechanical assemblies where permanent adhesion is undesirable. The compact 10ml size makes it ideal for field kits, gunsmithing shops, and maintenance toolkits where space is limited but reliable fastener security is non-negotiable. Application is straightforward: apply a small amount to the threads before assembly, allow cure time per manufacturer guidelines, and the fastener will remain secure against vibration and environmental stress while remaining serviceable when needed.
