Loctite 242 Automotive Threadlocker: High-Temp, Medium-Strength Anaerobic Adhesive | Red, 6mL Tube

LOCTITE Threadlocker 242 is a versatile medium-strength blue threadlocker designed for a wide range of applications. It is particularly effective for securing nuts and bolts sized from 1/4" to 3/4" (6mm to 19mm), offering a reliable alternative to costly lock nuts and washers. By preventing loosening caused by vibration, it ensures a secure and durable seal while protecting against thread corrosion. The adhesive is formulated with a medium viscosity methacrylate base, facilitating quick fixture times of 5, 15, and 20 minutes on steel, brass, and stainless steel respectively.

This thixotropic product prevents adhesive migration post-application and is specifically engineered for fasteners that require periodic disassembly using standard hand tools. Its operational temperature range of -65°F to 300°F (-54°C to 149°C) makes it suitable for diverse environmental conditions.

LOCTITE 242 excels in applications requiring steadfast adhesion and secure sealing of threaded fasteners, crucial for preventing loosening and leakage due to shock and vibration. It cures in the absence of air between closely fitting metal surfaces, ensuring reliable performance on less active substrates such as plated surfaces. This characteristic is particularly beneficial where routine disassembly is necessary for maintenance purposes.

In the automotive sector, LOCTITE products are not only specified by original equipment manufacturers (OEMs) but are also developed and rigorously tested in collaboration with auto manufacturers. They are trusted for assembling and maintaining engines in professional race cars, across both gasoline and diesel engines. LOCTITE adhesives, sealants, gasket makers, and coatings play a pivotal role in sealing, securing, and repairing critical vehicle components, from bolts and gaskets to cooling lines and core plugs.

The reliability of LOCTITE 242 extends to its ability to work effectively on all metals, including passive substrates like stainless steel, aluminum, and plated surfaces. It offers the convenience of being removable with hand tools, making it highly suitable for automotive and industrial applications where periodic maintenance or servicing is required. Its multi-purpose nature makes it ideal for securing valve cover bolts, water pump bolts, oil pan bolts, drive shaft bolts, rocker arm adjustment nuts, and carburetor studs.

With a curing time of just 5 minutes for initial setting and full curing within 24 hours, LOCTITE 242 enhances operational efficiency in assembly and maintenance tasks. This rapid curing time ensures minimal downtime while providing a durable and secure bond that withstands the rigors of automotive and industrial environments.

In summary, LOCTITE Threadlocker 242 stands out for its versatility, reliability, and ease of use in securing threaded fasteners across a broad spectrum of applications. Whether in automotive assembly or general industrial maintenance, its proven performance and trusted brand reputation make it a preferred choice among professionals worldwide.
