3M Scotch-Weld threadlocker anaerobic adhesives are one-component anaerobic adhesives that cure and seal threaded assemblies in a wide range of applications to prevent vibration loosening and/or leakage. All products provide excellent vibration, corrosion, and shock resistance. Engineered to provide different strengths, temperatures, nut/bolt sizes, and other requirements, some threadlockers allow removal and meet various selections depending on the specific application.

Features and Benefits

• TL22 is removable with hand tools. It is a low strength (low torque removal) threadlocker for small diameter, fine threaded screws, set screws, nuts, bolts, and hex and slot driven components such as keyed fasteners
• TL42 is a general purpose, removable with hand tools, medium strength threadlocker ideal for machine tool access bolts and hydraulic system bolts. It can also be used on gear box/driveshaft bolts, bearing cover cap screws, countersunk screws, and conveyor roller bolts
• TL43 is a general purpose, removable with hand tools, medium strength threadlocker for most medium and coarse-threaded screws, nuts, and bolts. It is oil tolerant to help secure as-received parts and its thixotropic property prevents run-off, dripping, or migration of the adhesive product when applied on parts
• TL62 is a medium to high strength threadlocker that is especially developed to secure assemblies with high strength retention. It allows disassembly with heat and will perform on lightly oily parts with only approximately 10% strength reduction
• TL72 is a permanent high strength threadlocker to lock bolts and studs up to 1” in diameter. It can be used for high-temperature threadlocking (intermittently up to 400°F), and its thixotropic nature prevents dripping or migration of the liquid adhesive after assembly
