Loctite 271 & 242 Threadlockers for Automotive: High-Strength & Medium-Strength Anaerobic Adhesives, Heavy-Duty & All Purpose Applications, Works on All Metals, Red & Blue, 36 ml Bottles

This automotive threadlocker bundle combines a high-strength red threadlocker and a medium-strength blue threadlocker to meet all your fastening needs. The LOCTITE 271 red threadlocker provides 3,000 psi of holding power for permanently securing large bolts, studs, press fits, and slip fits on heavy duty applications. It sets in 10 minutes and works on all metals. With its high viscosity formula and resistance to oils and vibration, LOCTITE 271 keeps parts locked even in demanding environments. Complementing it is LOCTITE 242, a versatile blue threadlocker ideal for small and medium threaded fasteners that require occasional readjustment. It sets in just 5 minutes and allows hand tool removal. Both threadlockers are OEM-approved and lab tested to lock threaded assemblies securely. With its combination of a heavy-duty red and a medium-strength blue threadlocker in one bundle, this package has your entire range of automotive fastening applications covered - from delicate components like carburetors to heavy duty parts like transmission assemblies. The two formulas work synergistically to eliminate the need for lock nuts, washers, or set screws.
