High-Strength Anaerobic Threadlocker
ThreadLocker Red H271 is a high-strength anaerobic sealer designed to lock and seal threaded metal fasteners. The 50 ml bottle cures in the absence of air to prevent loosening from vibration and to block leak paths that cause rust and corrosion. Initial cure occurs in 20 minutes with full strength reached after 24 hours.
Mechanics and Maintenance Teams
This product suits technicians securing bolts up to M36 on engines, pumps and structural assemblies where disassembly requires heat and hand tools. It is not intended for low-strength needs, plastic threads, or applications where frequent adjustment with hand tools alone is required.
Consistent Performance Under Load
The adhesive delivers an average breaking torque of 25.5 N.m on standard test fixtures and maintains its bond across an operating range of -58 to 302 degrees Fahrenheit. Viscosity of 400 to 600 mPa.s at 25 degrees Celsius ensures even coverage on coarse and fine threads during sustained vibration and thermal cycling.

Questions about this item
What screw sizes does the M6-M20 range on this H271 threadlocker cover?
The H271 is rated for fasteners from M6 up to M20, so it suits most automotive and industrial bolts in that span.
Will this red 25.5 N.m high-strength grade release with standard hand tools if I need to service the joint later?
At 25.5 N.m average breaking torque, the cured bond typically requires heat and heavy-duty tools for removal, not ordinary hand wrenches.
How do I confirm the 400-600 mPa.s adhesive has cured properly after the 24-hour period?
After 24 hours at room temperature the bond reaches full strength; attempt to turn the fastener — if it holds at the rated torque without movement, the cure is complete.
