Screw head size for MS24693?

[mhorowit]

MS24593 is a flat head machine screw with a 6-32 shank/thread. In this case it will be used to secure the steel bow on the trailing edge of the aileron to a wooden endpiece which is in turn, attached to the spar. It is countersunk into the endpiece so the diameter of the screwhead is important.

I went to HDepot and bought a 6-32 machine screw to see what length I needed (the original having rusted beyond recognition). I compared the Hdepot screw with the MS and noticed it was 1/4" dia. as compared to 3/8", so I'm wondering if I order the MS screw if the head will be large enough.

The difference I'm seeing is caused by the 100^ angle on the MS screw, but I don't know if the final diameter will match the original.

Would anyone with experience with this screw please weigh in? - Mike


Wait a second: problem solved. Blueprint shows a simple countersunk 6-32 machine screw.
I can use an AN526 with a washer under the head; problem solved. Thanks anyway - Mike

Mike:

I don't really understand your question, and you don't really need an answer, but I think the answer is 1/4". Actually, I mic'd it at .254"
