| Aerospace MS & AN Lock Nuts |
Mettec recommends
aircraft quality lock nuts. The threads are high quality which provides for smooth
torqueing action. On the AN 364/365 nylon insert nuts, nylon creates positive locking
through multiple use. The MS 21042 steel flanged nuts have a higher heat resistance and
strength rating. They have an ovalized top and are Moly coated to reduce friction on
titanium bolts. Visually inspect the locking area for wear, and replace the nut when you
feel the resistance starting to relax. For areas with repeated disassembly the AN 364/365
lock nuts are best. For maximum performance we suggest the MS 21042 lock nuts. |

These nuts feature a
good combination of light weight and high strength (160,000psi tensile). Available in
steel which is good up to a temperature of (450 F).

The crimp locking action needs lubrication in the Titanium to Titanium sliding interface
of the threads. |

These are the most common and
durable self-locking aircraft nuts. Almost infinitely reusable, tensile strength rated at
125,000 psi with a 250 F temperature
rating. Thin (AN 364) nuts should only be used in shear load applications. |
