Product Description
Permabond® HM118 is an excellent general-purpose anaerobic threadlocker designed for the permanent assembly of bolts, nuts, and screws. Formulated as a non-drip, thixotropic red liquid, it prevents vibration loosening and provides high off-torque strength once fully cured at room temperature. It cures reliably and rapidly on a wide variety of metal surfaces, including steel, cadmium, zinc, and other plated fasteners, making it highly effective for machinery and equipment manufacturing.
Key features
- Military and ASTM approved: Tested to meet the stringent requirements of MIL-S-46163A and ASTM D5363 (sections 5.1.1, 5.1.2, and 5.2).
- High structural strength: Delivers a high breakaway torque (23 N-m) for permanent assemblies, effectively preventing loosening caused by vibration.
- Application versatility: The thixotropic nature ensures the adhesive remains in place on threads, while simultaneously lubricating those threads to facilitate easier assembly.
Applications / Suitable for
- Permanent assembly of bolts, nuts, and screws (up to M20 / 3/4")
- Locking fasteners on steel, cadmium, zinc, and other plated surfaces
- Machinery and equipment manufacturing environments
