Permatex 27005 is a high-strength red gel threadlocker designed to permanently lock bolts, screws, studs, and press-fit assemblies. This gel-based adhesive prevents fasteners from loosening due to vibration and movement, making it essential for automotive, industrial, and household applications where fastener reliability is critical. The non-dripping gel formula delivers 3000 psi holding power on slip and press-fit assemblies, effectively replacing set screws and snap rings while simplifying assembly processes.
The thick, non-runny consistency eliminates mess, drips, and waste by staying exactly where you apply it. This precision application is especially valuable for professional mechanics and DIY enthusiasts who need controlled placement on small fasteners. The compact 5-gram tube is portable and convenient for toolboxes, service kits, or job sites, reducing clutter while providing reliable fastening power.
