Dual-Strength Threadlocker Set
This set includes a 50ml bottle of medium-strength blue threadlocker and a 50ml bottle of high-strength red threadlocker. It is designed for mechanics, technicians and DIY users who need to secure threaded fasteners against loosening and corrosion across a variety of automotive, industrial and furniture applications.
Curing and Holding Performance
The compound begins to cure in 20 minutes and reaches full strength within 24 hours, forming a durable bond that resists vibration, shock, humidity and extreme temperatures. The blue formula allows disassembly with standard hand tools, while the red formula provides a permanent lock for critical assemblies that must not come loose.
Liquid Application and Sealing
The liquid threadlocker flows into thread gaps to create a waterproof, heat-resistant seal that replaces traditional gaskets and lock washers. Each 50ml bottle features a nozzle for precise application directly onto bolts and nuts, reducing waste and eliminating the need to stock multiple specialised locking components.

Questions about this item
Will the 50 ml bottles of threadlocker cure fast enough for a full day of shop work?
Initial cure takes 20 minutes and full cure is reached within 24 hours, so parts handled the next shift will be fully locked.
Do I need any extra tools or primers to apply the blue and red threadlocker?
Apply the liquid directly to the bolt and nut threads, tighten, and let it cure — no extra tools or primers are required.
Can I still remove bolts later if I use the medium-strength blue threadlocker on older fasteners?
Yes, screws coated with the medium-strength blue threadlocker can be removed directly with standard hand tools.
