- Red anaerobic formula locks fasteners up to 3/4 in diameter

Red High-Strength Threadlocker
Loctite 262 is a red anaerobic adhesive that locks and seals threaded metal fasteners up to three-quarters of an inch in diameter. It develops a breakaway torque of 190 in-lb after full cure and meets ASTM D-5363 and MIL-S-46163-A standards for permanent assembly.
Bottle Format and Primer Compatibility
The 10 mL bottle dispenses liquid directly onto threads and offers an eight-minute working window before the adhesive begins to set. Surfaces contaminated with oil do not prevent curing, and Loctite 7649 primer can be used to accelerate the reaction on inactive metals or large gaps.
Permanent Metal Fastener Locking
This product suits maintenance and assembly tasks where bolts, studs or pipe plugs must resist vibration and shock without the possibility of later disassembly. It is not intended for plastic threads, low-strength requirements or applications that need routine adjustment.

Questions about this item
How can I confirm the 262 Red threadlocker has cured properly after the 8 min working time?
After assembly, allow the anaerobic cure to complete; a fully cured joint will resist disassembly with approximately 190 in-lb breakaway torque on the specified metals.
What is included with the 10 mL bottle and do I need to buy Loctite 7649 primer separately?
The package contains one 0.34 fl oz bottle of red high-strength liquid threadlocker; primer 7649 is compatible but not included and must be purchased separately if required.
When should I choose the 262 Red 10 mL version instead of a different strength or size?
Select this 262 Red high-strength grade for permanent locking on fasteners up to 3/4 in diameter on brass, bronze, copper, iron, manganese, Monel, nickel or steel where maximum breakaway torque is needed.
