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). |

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.
Highest quality, provides a light weight low profile locking fitting. Great for high heat applications.
As described. Recommended.
Perfect! Great product and much cheaper than other manufacturers. This is my go to shop for my race car needs.
Just what I needed.
