0TreeLemur Posted April 30, 2019 Report Posted April 30, 2019 Okay- got your attention. Mind out of the gutter. I bought a pair of Orion 650 wingtip nav/strobes recently for a good price. While cleaning them up this past weekend, I noticed that one of them is missing an internal mounting screw, which is a MS24693-C2 (see #6 below). Of course Aircraft Spruce doesn't stock it. Anybody know of a good source? Thx. Quote
larrynimmo Posted April 30, 2019 Report Posted April 30, 2019 you can buy screws like that from amazon...I have done so in the past Quote
0TreeLemur Posted April 30, 2019 Author Report Posted April 30, 2019 Yeah, I just looked- they sell them in lots of 5000 for about $200. Don't see anyone selling them by ones and twos. Quote

Maybe that is the way to go. Buy 1/2" so I'll have plenty of room to clamp the non-head end in a vice and Dremel them down to length with a nut on to repair the thread. <whinge>Just, UGH. I'd rather not have to do that! </whinge> Quote

But many of the cheap wire strippers have threads for small screws/bolts, including the 4-40 you need, which will enable you to trim them precisely with relative ease. Here is not such a cheap example from Spruce for $20, but you can probably get something similar from Home depot for half the cost. https://www.aircraftspruce.com/catalog/topages/crimptool.php?clickkey=174964 Edited April 30, 2019 by kortopates Quote

Hank Posted April 30, 2019 Report Posted April 30, 2019 Is therr a Storeroom Fastener nearby? Little ol' Auburn has one . . . . Quote
0TreeLemur Posted April 30, 2019 Author Report Posted April 30, 2019 Nope. Ace Hardware is about as good as it gets in T-Town. I went ahead and ordered 5/8" long #4 SS screws from Aircraft Spruce. I'll put a couple of nuts on then cut them to length with a Dremel. Quote

vorlon1 Posted April 30, 2019 Report Posted April 30, 2019 Looks like a screw used in securing computer daughter boards to the case... I'm guessing a freebie from the local Best Buy? Quote
Andy95W Posted April 30, 2019 Report Posted April 30, 2019 The problem is the 100° countersink. Most non-aviation screws are 82°. 4-40 screws are skinny and very easy to cut with a common crimping tool. After that, you can use it as a crimper, to boot. 1 Quote
rbridges Posted April 30, 2019 Report Posted April 30, 2019 have you tried contacting whelen directly? Quote
David_H Posted May 1, 2019 Report Posted May 1, 2019 (edited) It seems like the easiest course of action would have been to buy the 100pcs from McMaster for $11 + shipping since they are the exact screw. I think the McMaster image posted shows the identical part number as well. A fellow has to ask themselves how much their time is worth. Edited May 1, 2019 by David_H 1 Quote
carusoam Posted May 2, 2019 Report Posted May 2, 2019 It’s at least 0.010 amu worth of humor... Good luck with the cut and reorganizing the threads. Whelen is in CT if you want to call them... to enact Plan Bravo... Best regards, -a- 1 Quote

If someone had offered one of the MS24693-C2 for $10 it would have been an easy fix. But what to do with the other 99 .. .lol? 1 1 Quote
0TreeLemur Posted May 2, 2019 Author Report Posted May 2, 2019 I have an electrical wiring stripper/tool with an integral shear that will make short work of turning a 5/8" long #4 SS screw into a 1/4" long one, and fix the threads to boot after the cut is made. 1 Quote
