Guy's I am looking for some 5-40 x 1 1/4" allen socket screws. I found some at the price of .39 ea in lots of ten, plus shipping.
Does anyone have any other ideas?
Thanks,Gil

I'd try someplace like SmallParts or MSC. I buy boxes of a 100 4-40 and other sizes from SmallParts for like $8.00

Thanks guy's, I went to Mc Master-Carr and the 5-40 vary in thread length from 3/4" to 1 3/16" with no guanteree of the 1 3/16" length of threads. Will keep looking. Using these for axel's on L/G w/ wheel pants...

The first place to look is the nearest Ace Hardware if you are looking for the odd bits that we require.

Larry, I went to the local Ace and told the gent what I was looking forand he asked "Is that metric?" I told him that it is a #5 machine screw with 40 threads per inch. But, they didn't have them anyway...

Hey, mind describing your set-up? Does 5-40 fit something generally, like brass tubing, or is it strictly for a specific set of wheel pants? or??

I have about 75 of them. E-mail me your address. Name what you want, and pay for postage is all I want.

There is a certain GPS directed artillery shell that uses 5-40 screws to hold on the nosecone. Only place, other than C*X that I have ever seen the call-out.

#5-40 UNC (same diameter as 1/8" BSW) fits 5/32" brass tubing which has a bore of 1/8". Great for bushing plastic hub wheels.

Larry, I am using them because they fit in side the 1/8" I D brass tubing that I use as wheel bearings in the plastic wheel hubs.
They fit just right.
Dale G also told me about 3mm bolts located in the car section of hobby shops. Will look at them also...

Eyeballing it, I thought (hoped) that might be the case! That is a great tip, as other combos are off a tad. I couldn't find the specs to confirm the fit, but your hands-on experience is better confirmation than comparing numbers.

I am going to steal your idea.

Yes, for .39 each in lots of 10. Isn't that the price he was trying to beat?

None of the suggestions that anyone has given here appear to be any cheaper. Some are far more expensive. I did some looking, too, and didn't come up with any good alternatives. However...

Since you are wanting to use these as axles with an 1/8 inch bushing, Matt uses 4-40 bolts on his planes with wheel pants. You just put the next smaller tube over the 4-40 bolt and make it a bit wider and then tighten it down so it doesn't turn. You now have a smooth surface on the axle for the bushed wheel that you are wanting to use, and you can use more readily available (and somewhat cheaper) 4-40 bolts.

Hey Lenoard:
Mine is cheaper because it eliminates the shipping..

Have found some stainless in the car section, lot more than 39 cents per screw and the longest I could find was only 3/4 inch. would like to get some 1 1/4 titanium 5-40 screws but that is like finding a stock Fox 35 that doesn't shake or burp.
