Material Notes:

Permabond® HM128 Threadlocker is a high strength adhesive for permanent assembly. It is typically used for preventing vibration loosening of bolts, studs and cap screws. Full cure to a cross-linked plastic is achieved reliably and fast on steel and all common bolt platings. Additional application areas include machinery, equipment, and electric motor manufacturers. PERMABOND® HM128 Threadlocker replaces lock washers. Features & Benefits: Prevents vibration loosening Controlled off-torque Permanent threadlocking Full cure at room temperature Lubricates threads for easier assembly Provides corrosion protection Superior environmental resistance Environmentally friendly – 100% solids Information provided by Permabond.
