Loctite Threadlocker Blue 242 is a medium-strength, all-purpose adhesive designed to lock and seal all types of nuts, bolts, and other fasteners.

It is ideal for fastening applications from 1/4” to 3/4”, providing heavy-duty assurance against vibration, rust and leakage. Compared to this glue, which is a thread lock type glue, it sets in 10 minutes and fully cures in 24 hours.

This makes it fast and reliable for use in small engines, lawnmowers, and power equipment. It tolerates harsh temperature ranges, from -65°F to 300°F and performs well on stainless steel or plated metal.

What makes it different is that it removes with just hand tools, allowing you to save time and have more flexibility when adjustments are required.

Medium Strength and Easy Removal

Loctite Threadlocker Blue 242 is ideal for medium-strength removal with tools. It is extremely effective at locking bolts and fasteners from 1/4 inch to 3/4 inch diameter. Its formula strikes the ideal strength, offering just the right amount of holding strength to keep everything in place.

Changing it up is simple and quick, with no strings attached. This tool is the most versatile tool I’ve ever used. Its versatility from automotive repairs to home crafts means you always have the medium strength you need for any project.

What makes it special is how easily it makes disassembly possible with common hand tools. Lock high-strength fasteners in place with confidence! They will remain tight under use and won’t give you a migraine while servicing.

This easy removal feature ensures convenience, making it an ideal choice for projects that may need updates or replacements from time to time. I’ve found it to be reliable for maintaining tightness of bolts on equipment and general use hardware.

Install it one time, and you won’t have to worry about anything coming apart at a surprise moment.

Thread Protection and Corrosion Resistance

Loctite Threadlocker Blue 242 is a trusted threaded fastener protection against rust and corrosion. A hard, safe, corrosion resistant envelope develops around metal threads, shielding them from wear. This significantly increases the service life of nuts and bolts, even in wet or harsh conditions.

This added layer of protection greatly reduces the chance of corrosion, ensuring your hardware will remain out of harm’s way for years to come. I put it through the paces on outdoor gear that had been rained on. To our amazement, the threads remained free of rust after months of application!

Its exceptional protection against leaks in metal threads provides a safe, reliable seal. It is highly effective at preventing fluid or gas leaks. Whether it’s threaded protection for automotive components, industrial machinery, or plumbing fittings, it provides confidence and corrosion defense.

I’ve run it through my personal small engine and the seal has never dripped or loosened. Non-staining formulation allows compatibility with stainless steel and plated surfaces making it ideal for multiple materials. This is particularly advantageous when fabricating with dissimilar metals.

It maintains a powerful hold without causing damage to the substrate’s surface finish. I’ve used it for securing bolts on stainless steel appliances. It worked perfectly, with the surface unmentioned and robust.

For nuts and bolts sized from 1/4 to 3/4 inch, it does an excellent job of stopping leaks and rust. I’ve used it to lock down an optic mount on my pistol. Multiple hundreds of rounds later, the optic remained solid and true with no need to readjust.

Quick Setting and Curing Time

Loctite Threadlocker Blue 242 is the time-saving solution that does not cut corners on performance. Setting in only 10 minutes, it’s ideal for when you need to stay on schedule. Whether it’s a stopgap repair or you’re preparing components for a more in-depth project, fast setting time helps you be fast and productive.

You can get more done in a day without spending time waiting in a queue. Tightening bolts on a bicycle or clamping down small machine components is a snap. You can have confidence that the adhesive will create a strong, lasting bond within minutes.

Completion of the full 24 hours curing time provides a strong, permanent bond that is resistant to long-term use. The balance between quick initial setting and long-lasting curing is remarkable.

This combination makes this a particularly attractive solution for projects where both reliability and speed are imperative. I’ve since found it easy and convenient enough to use that when I needed a quick but permanent solution for a furniture repair I reached for it again.

It did everything it claimed to do, painlessly and smoothly.

Wide Compatibility with Materials and Sizes

Loctite Threadlocker Blue 242 is exceptional in its versatility, being compatible with almost all fasteners and materials. From the smallest of screws to bolts of 1 inch in diameter or more, you can rely on it to deliver a sturdier grip. It’s tough and versatile enough to wear through any task.

This wide compatibility with various materials and sizes makes it a versatile option for any project at home, in the shop, or on the job. It’s as much at home on fine electronics as it is on auto repair. This allows you to avoid having to buy different products for different steps!

Its effectiveness on a wide variety of materials and surfaces only adds to its versatility. From metal to wood to plastic and all common materials in between, it creates a durable bond without the need for additional tools or mixing steps.

It’s wide compatibility with materials and sizes fits a variety of common day-to-day needs. I’ve used it for putting together furniture and recently even fixing my bike.

Vibration Resistance and Durability

Loctite Threadlocker Blue 242 is the industry standard for locking down threaded fasteners. It truly resists continuous vibration, so you never have to worry about your connections loosening up. This detail is particularly beneficial to applications involving heavy-duty movement, such as automotive components or power tools.

By stopping vibration induced loosening it protects long-term performance with no maintenance, saving time on subsequent re-torquing or reapplicating. For example, if you’re working on a motorcycle engine or securing bolts on a lawn mower, you can rely on this threadlocker to stay in place.

Its vibration resistance and general durability merit mention as well. Built to withstand extreme conditions, it won’t lose its grip in rugged environments. Whether facing the rigors of moisture, dust, or the everyday grind, it stands up without faltering.

With its outstanding temperature tolerance, it flourishes in environments from -65°F to 300°F. Whether you endure ice-cold winter mornings or the blistering heat of a hot engine, it readily adjusts to either extreme.

Reviews

For thread locker, I’ve always had a lot of luck with Loctite’s ‘Blue’ 242. It’s my favorite for locking down fasteners on builds where vibration is an issue. I’ve done the nail polish fix in a pinch, but have never had a full bottle last as long as this one does.

This product is really awesome! Saying it off as ‘acetone-soluble varnish’ on specs is funny, but the performance difference is very apparent.

Types of Removable Thread Lock Glue

Removable thread lock glue is available in several types of formulas, each tailored for a unique application or material. Some are more appropriate for metal fasteners, while others can accommodate more complex materials, such as mixed plastics and composites. These varieties let you select the ideal adhesive for your task without sacrificing performance.

For instance, Loctite Threadlocker Blue 242 is perfect for use on metal threads, thus making it a great all-around go-to for most jobs. Beyond removable thread lock glue, there are low, medium, and high-strength adhesives, which serve various fastening requirements.

Low-strength removable thread lock glues are best for smaller screws and bolts that you want to be able to adjust from time to time. Medium-strength options, such as Loctite Threadlocker Blue 242, offer enough holding power to keep fasteners secure, but allow for the removal of fasteners with general purpose tools.

High-strength adhesives, in contrast, are more permanent and are commonly used in heavy-duty applications. This versatility is what makes removable thread lock glue the perfect choice for most professional and DIY applications.

No matter if you’re building equipment or doing DIY projects around the house, there’s a removal formula to suit your application.

Proper Application Techniques

For optimal performance from Loctite Threadlocker Blue 242, clean surfaces are a must. Any dirt, oil or debris on the threads can compromise the bond. I’ve found a little rubbing alcohol or degreaser is helpful in cleaning.

Allow the threads to dry thoroughly before proceeding. This step may look minor before a product takes hold, but it goes a long way in ensuring a strong hold product.

Application rateUsing the proper amount when applying is equally critical. Just a small drop of the threadlocker will be sufficient for most screws and bolts. Putting in too much can create a distracting clutter, and worse, it may be more difficult to remove later.

I like to distribute the product uniformly down the threads to avoid any high spots and too much product.

Patience goes a long way when setting and curing. Once you’ve applied, allow it adequate time to set to ensure a solid bond. Loctite Blue 242 usually fully cures in 24 hours at room temperature.

If you’re working on something that’s really that important, waiting makes sure you have a strong grip. I’ve noticed the product works best when allowed to cure undisturbed, so planning ahead can save you time and hassle.

Buying Guide

Loctite Threadlocker Blue 242 generally ranges from $5-$15, depending on where and how you buy it. The price varies based on the size of the bottle and which retailer you purchase from. For less complex projects such as the upkeep of household implements, the low end of the scale may be adequate.

For high vibration environments, such as machinery or automotive components, it prevents loosening due to shock or vibration.

Warranty and return policies vary greatly by retailer, so be sure to check what they offer. Some stores will have a satisfaction guarantee, others will have no return or exchange policy at all.
