Bottom line is that I am so glad that I ordered new fasteners for the interior of my plane. As I sat down to order them (this review applies to all of the fasters) I learned that very few of the screws in the plane (installed by previous owner) were the proper screws per the parts manual (which called for cadmium plated screws.) Parts arrived quickly with excellent packaging. The mechanic said he appreciated them and they really made it easier to put everything back together.

Its astonishing how such a small, inexpensive part as the Maule tail wheel locking spring--a coil about an inch long and less than 1/4 inch in diameter--can affect the performance of an airplane! Aircraft Spruce sent it by first class mail (as I requested) and it arrived in a couple of days. Fits perfectly and easy to install.

I ordered the Maule TW-15A steering arm subassembly. When it arrived, the locking ring had not been machined completely. The lock pin holes were absent and the through hole was undersize. Aircraft spruce was very prompt about helping me diagnose the problem. They sent a replacement immediately and provided a will call tag to return the nonconforming part. I would rate their customer service as top notch.

Q: Are these 10-24 machine screws course thread?

Yes, a 10-32 thread would be considered fine thread, 10-24 is a coarse thread.

Q: Is MS35206-243 non-magnetic? Our customer has asked for this part number while mentioning Non Magnetic.

Part number MS35206-243 is made of CAD plated steel, and is magnetic. We do not have any ins stock, but we can try to special order AN515B8-6, which is the previous spec to this MS style screw, but made of brass and not magnetic. Please advise how many you need so we can try to locate them for you.

Q: With the MS35207 & MS35206 Machine screws, can you get any of them in Stainless?

It appears that stainless steel is not an option available per the data sheet. This is only available in carbon steel with either a cadmium plating or a zinc coating.

Q: Does spruce sell any nuts compatible with these ms35206-203 screws?

Yes see part # 04-01357.

Q: The MS35206-263 can be considered as 10-24 UNC-2B? thks

The milspec comes up as 10-24 UNC-2A.
