Permabond® LM113 Threadlocker is a medium viscosity product for locking small threaded fasteners, such as screws and bolts or hydraulic fittings that might require disassembly. Due to its thixotropic viscosity, the liquid adhesive will not run away from the area of application. PERMABOND’s LM113 Threadlocker cures reliably and fast on steel, cadmium, zinc and other plated fasteners.
FEATURES AND BENEFITS
- Prevents vibration loosening
- Controlled off-torque
- Full cure at room temperature
