? Screw head diameter?
MS24593 is a flat head machine screw with a 6-32 shank/thread. In this
application the diameter of the screwhead is important. I went to HD and bought a 6-32 machine screw to see what length I needed (the original having rusted beyond recognition). I compared the HD 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 the MS24593 screw please weigh in? - Mike |

Would anyone with experience with the MS24593 screw please weigh in? - I would be very curious as to what the application is for this screw. If it is going to be any more important than holding a radio in the panel, then you need to be thinking about the quality and strength of the screw. HD screws have no strength guarantee, compared to a MS screw. They may have only 10% of the strength of a MS screw. If that is the case, the head size is the least of your worries. I hope you are not using hardware store screws in your homebuilt for any important functions. You are gambling your life. You could be a _big_ looser. -- Jim in NC |

No, no, no, no We do not use hardware from Home Depot Aerospace for anything except non-structural things like holding the floorboards in place. I mentioned HD and the cml screw because I thought the cml screw would have the same profile as the MS screw and I could use it as a model of what to purchase. What I didn't realize is that the underside angle of the head (countersink) for the MS screw was different from the cml screw, so that was a good idea gone bad. Still don't know if a #6 MS24694 is going to give me a 3/8" dia head. |

A 6-32 countersunk screw with a 3/8" diameter head? Even a 10-32 screw with a 100° countersink will barely be 3/8". If you meant 3/16", then the difference in the head diameter is due to the 87° or 90° countersink on the hardware store screw. |

Blueprint shows a simple 6-32 machine screw used vice the flat head; I'll take that approach using an AN526 and countersink that - Mike |
