Have you ever faced the annoying problem of your nuts and bolts coming loose due to vibration, shock, or corrosion? If you have, you know how frustrating and dangerous it can be, especially if you are working with critical components like engines, gearboxes, or suspension systems. You don’t want to risk your safety or performance because of a loose fastener, do you?
Fortunately, there is a simple and effective solution to this problem: using a threadlocker. A threadlocker is a special type of adhesive that locks and seals threaded fasteners, preventing them from loosening or leaking. Threadlockers come in different colors, indicating their strength and removability. In this article, we will focus on one of the most popular and versatile threadlockers: Blue Thread Locker 242.
What is Blue Thread Locker 242?

Blue Thread Locker 242 is a medium-strength, medium-viscosity, anaerobic-curing threadlocker that offers general-purpose qualities. It is based on dimethacrylate-ester and cures when confined in the absence of air between close-fitting metal surfaces. It is suitable for all metal fasteners up to 3/4 inch (20 mm) in diameter.
Blue Thread Locker 242 is ideal for applications that require normal disassembly with standard hand tools. It eliminates the need for stocking expensive lock nuts and lock washers, and locks and seals while preventing parts from loosening due to vibration. It also protects threads from corrosion and galling.
What are the Features and Benefits of Blue Thread Locker 242?
Blue Thread Locker 242 has many features and benefits that make it a great choice for securing your nuts and bolts. Here are some of them:

– It has a fast fixture time of 5 minutes for steel, 15 minutes for brass, and 20 minutes for stainless steel.
– It has a full cure time of 24 hours at room temperature, which can be accelerated by using activators such as 7471, 7649, 7088, or 7091.
– It has a working temperature range of -65°F to 300°F (-54°C to 149°C), making it suitable for various environments and conditions.
– It has a breakaway torque of 110 in-lb (12.4 Nm) and a prevailing torque of 43 in-lb (4.9 Nm), meaning it provides a medium level of resistance to loosening.
– It has a shear strength of 145 psi (10 N/mm2), meaning it can withstand moderate loads and stresses.
– It is resistant to contamination from anti-corrosion fluids and various industrial oils, such as motor oil, transmission fluid, and cutting oil.

How to Use Blue Thread Locker 242?
Using Blue Thread Locker 242 is easy and straightforward. Here are the steps you need to follow:
1. Clean and dry the threads of the fasteners and the mating parts. Remove any dirt, grease, oil, or other contaminants that may affect the bonding.
2. Shake the bottle of Blue Thread Locker 242 well before use.
3. Apply a few drops of Blue Thread Locker 242 to the threaded portion of the fastener, enough to fill the gaps between the threads. Avoid applying too much or too little, as this may affect the performance of the threadlocker.
4. Assemble the parts and tighten the fastener as required. Do not over-tighten, as this may cause damage to the threads or the parts.
5. Allow the threadlocker to cure for 24 hours at room temperature, or use an activator to speed up the curing process.
6. To disassemble the parts, use standard hand tools and apply normal force. If the fastener is difficult to remove, apply localized heat to the nut or bolt, such as a blowtorch, to weaken the bond of the threadlocker.
