Overview
|
The MS21042 all-metal stop nuts are designed for use in high temp installations (up to 450°F). MS21042 nuts are shorter than the AN363 nut but develop the same tensile strength. MS21042 Hex Nuts (Lubed) are the same as MS21042- but have a dry film lube (dark grey). Less 20% for quantity 100/Part No. |

Purchased these stop nuts for head nuts on Lycoming O-145 engine. Access is extremely tight. These worked perfectly.

Order shipped promptly, sales person very polite
Great nut for small tight places and firewall forward where heat is an issue.
Use these on my race car to reduce weight and ensure a secure fit.
