About Loctite
Loctite is one of the most recognized names in adhesives, sealants, and surface treatments worldwide. A Henkel brand built on more than six decades of chemistry innovation, Loctite traces its roots to the 1953 invention of anaerobic threadlocking technology — a breakthrough that would permanently change how engineers and technicians secure fasteners. Today, the brand's product line spans acrylics, epoxies, anaerobics, cyanoacrylates, silicones, urethanes, and UV-cure formulations used across maintenance, manufacturing, and the automotive aftermarket.
What sets Loctite apart is a reputation earned in the most demanding environments. Loctite thread lockers, gasket makers, and structural adhesives are not just widely available — they are OEM-specified and track-tested by vehicle manufacturers at the highest levels of motorsport, including Formula One, NASCAR, and Indy Racing League. That heritage translates directly to the garage, shop floor, or jobsite where reliability is non-negotiable.
Why Mechanics and Engineers Trust Loctite
Professional technicians often say they can only afford to do a job once. Loctite builds its entire product philosophy around that reality. Each formulation is engineered to perform correctly in real-world conditions — resisting vibration, moisture, temperature extremes, and chemical exposure. Whether you're sealing a hydraulic fitting, locking down a critical fastener, or bonding dissimilar materials, Loctite offers a product dialed in for that exact application.
The lineup is organized by chemistry and strength, making it straightforward to choose the right solution. Threadlockers range from low-strength removable grades (like the familiar Blue 242/243) to permanent high-strength formulas (Red 271) for critical fasteners. Gasket sealants include both form-in-place anaerobic gasketing compounds and RTV silicone products for flanges, valve covers, and oil pans. Thread sealants fill the space between threaded pipe and fitting connections, curing in the absence of air to create leak-proof, pressure-tight joints. And the Loctite epoxy adhesive range — including the Hysol and EA series — delivers structural bonding strength for metals, composites, and plastics in both repair and assembly applications.
A Product Line Built for Every Level of the Trade
From a quick bolt repair on a lawnmower engine to a full assembly line in a manufacturing facility, Loctite's breadth means there's a purpose-built solution available. The brand's color-coded and numbered system (222, 242, 271, 567, 592, and many more) has become a universal language among technicians — when someone says "use blue Loctite," every mechanic in the shop knows exactly what that means. That kind of cultural recognition is earned, not marketed.
