  • FeaturesStrong
  • Prevents rust and corrosion on metal fasteners

  • Anaerobic cure starts in 20 minutes at room temperature
  • Full strength reached after 24 hours for permanent bonds
  • Half-filled 50 ml bottle keeps adhesive liquid until use

Medium-strength anaerobic threadlocker

ThreadLocker Blue M243 is a medium-strength anaerobic sealer supplied in a 50 ml bottle for nuts, bolts and fasteners from M6 to M20. It cures in the absence of air to prevent loosening caused by vibration and protects metal threads from rust and corrosion.

Curing time and temperature range

Initial cure is reached in 20 minutes and full cure completes in 24 hours at room temperature. The adhesive remains stable across an operating range of -58 to 302 degrees and the half-filled bottle prevents premature solidification inside the container.

Holding power under sustained load

Average removal torque measures 5 N.m while average breaking torque reaches 12.4 N.m, giving reliable retention on assemblies that see continuous vibration. The product is not intended for high-strength permanent locking above 25.5 N.m or for fasteners larger than M20.

Questions about this item

How do I apply the M243 threadlocker and how long before the assembly can be used?

Apply evenly to threads, tighten the nut, allow initial cure for 20 minutes, then full cure in 24 hours before normal use.

Will the cured M243 need to be replaced or maintained over time?

The anaerobic bond prevents loosening and corrosion permanently; no scheduled replacement is required unless the joint is disassembled.

What is the highest continuous temperature the M243 bond can withstand before losing strength?

Operating range is -58 to 302 degrees, so sustained heat above 302 degrees is the first limit encountered.
