Threadlockers

Threadlockers

 Invented by Loctite Corporation, now Henkel Corporation as a revolutionary method to lock and seal threaded fasteners. Loctite® brand liquid threadlockers have found wide acceptance in a wide range of applications – From delicate electronic components to heavy construction equipment.

     Loctite brand threadlockers are available in varying viscosities and strength for virtually any application, including exposure to extreme environments. 

     Removable Strength. Bolt reusability is important in maintenance and repair work. Threadlockers with low to medium strength can be loosened without damage to bolts with ordinary tools.

      222 Threadlocker Low Strength/Small Screw
     Low strength threadlocker. Designed for precision metal fasteners under 3/4". Protects threads from rust and corrosion. Removable with hand tools. Available Worldwide Typical Applications Set screws, adjustment screws, calibration screws, meters, gauges.

      242® Threadlocker Medium Strength
    A general purpose, removable threadlocker for fasteners between 1/4" and 3/4" (6 to 20 mm) diameters. Controlled lubricity for accurate clamp loads. Parts can be separated using hand tools. 

     Typical Applications
     Machine tools, presses, pumps, compressors, mounting bolts, gearboxes.
 
     Approvals/Specifications
     MIL-SPEC S-46163A Type II, Grade N ; NSF/ANSI 61 

     243 Threadlocker Oil Resistant/Medium Strength
     A general purpose, medium strength threadlocker with improved oil tolerance. For fasteners between 1/4" and 3/4" (6 to 20 mm) diameters.

      Typical Applications
     Machine tools, presses, pumps, compressors, mounting bolts, gearboxes. 

     Approvals/Specifications
     NSF/ANSI 61 

     Permanent Strength. 
    These products are intended for products that do not require disassembly. If disassembly is required, use localized heat and hand tools.
