Permatex® Threadlockers are primerless, fast-curing anaerobics with excellent gap-filling, capillary action, and chemical resistance. Low, medium, and high-strength compounds provide excellent shock/vibration resistance. Penetrating grades have superior wicking, and retaining compounds provide higher strength than shrink or pressed fits. All qualify under MIL specs.
