MM115, HM118, HH120, HM128, HM129, HH131, HL126, LM113, A011–A1042 anaerobic threadlockers (MIL-S-46163A, MIL-S-22473E, ASTM D5363)
Country: United Kingdom · Model: MM115 / HM118 / HH120 / HM128 / HM129 / HH131 / HL126 / LM113 / A011–A1042
The one-component anaerobic threadlockers MM115, HM118, HH120, HM128, HM129, HH131, HL126, LM113 and the A011–A1042 series polymerize without access to air in contact with metal. Strength is from 5 to 17 MPa, viscosity from 10–30 to 7000 mPa·s. The compound fills the micro-gaps of the threads and keeps the fastener from loosening under vibration.

Description
The methacrylate compound stays liquid in air, and in the gap between metal surfaces it quickly cures into a plastic. Applied to the thread before assembly, it fills the threads, seals them and protects them from corrosion. In aviation such threadlockers are used throughout the aircraft, most of all in the engine and units. The low-strength LM113 and A011 (5 MPa) are intended for small diameters and frequent disassembly. The medium-strength removable MM115 (10 MPa), A113, A130 and A1042 (12 MPa) are removed with ordinary tools, the A130 is thixotropic, and the A1042 is fast-curing for hydraulics. The high-strength HM118, HM128, HM129, HH120 and HH131 give 17 MPa. The HM129 is rated for threads up to 1 inch, the heat-resistant HH131 up to 1½ inches, and the HH120 has a viscosity of 7000 mPa·s and is used for large bolts. The capillary HL126 (10–30 mPa·s) is introduced into already assembled joints. The activators A905 and ASC10 speed up cure on passive metals, in particular stainless steel.
How to choose
Strength and the method of disassembly decide everything. For frequent disassembly take the LM113 or A011, for disassembly with ordinary tools the MM115, A113, A130 or A1042, and for permanent assemblies the HM128, HM129, HH120 or HH131. The MM115 Pure is certified to NSF/ANSI 61 for contact with drinking water. The grades are listed in MIL-S-22473E, in particular HH120 Grade AVV, HL126 AA, MM115 CVV, LM012 HVV, and in MIL-S-46163A. For new designs ASTM D5363 is applied, and the MIL specifications apply to existing designs.

FAQ
Which threadlocker can be disassembled with ordinary tools?
The medium-strength MM115 (10 MPa), A113, A130 and A1042 (12 MPa).
Which threadlocker should be used for large bolts and hot assemblies?
The HH120 with a viscosity of 7000 mPa·s for large bolts and the heat-resistant HH131 up to 1½ inches. The HM129 is rated for threads up to 1 inch.
Which threadlocker can be used with drinking water?
The MM115 Pure, which is certified to NSF/ANSI 61 for contact with drinking water.
What should be done on stainless steel, where cure is slow?
Use the activators A905 or ASC10, which speed up cure on passive metals and coatings.
What should be used to apply the threadlocker to an already assembled joint?
The capillary HL126 with a viscosity of 10–30 mPa·s. It is listed in MIL-S-22473E Grade AA and MIL-S-46163A Type III/R.
