|Castle type nuts manufactured to MIL Specification MS21025 using 4140 steel. Mild steel nuts are not acceptable for use on certificated aircraft. 1-1/4" dia. nuts for 500 x 5 axles, 1-1/2" dia. nuts for 600 x 6 axles.|
I bought these because I needed 1-1/2-16 threaded nuts for a non-aircraft project. Its a hard to find thread size but Aircraft Spruce provided the solution..
Perfect as advertised.
High quality and a perfect fit.
Great Product, Great Fit. Steve
Fit my Cessna 150 Axle fine - its a Cessna PN replacement. Allowed me to take off the ugly nut for wheel pants and put on a hub cap.
got here ok
These nuts were absolutely perfect!
Great item, fast service, great transaction!
POORLY made. Threads gap where the pin goes in. Thread cut is ragged. Not exactly round. Thin walled. Would not recommend.
The dimensions of 06-11815 are 9/16 inch height x 15/16 inch outer flat side. Looking at the drawings in the "Drawings" tab, these would H and F. For reference, G is 1-1/16 inch.
It is a Mil Spec part, so as long as the aircraft manufacturer calls for this as a replacement part, it would apply to a certified aircraft. Similar to AN bolts and nuts.
