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).

widely used among F-1600 racers to ensure the AN bolts that match are held in place correctly- be careful not to over torque the smaller sizes
