Good machine shop?

Working on a project and I was given a “special screw” with “special threads”
Its short by about 1.5"
I’ve been to depot, lowes, hectors, value etc and no One has this screw.
I’m sick of looking and would rather have someone make me what I’m looking for.

Anyone know of a place that could make me 3 screws with the thread count I’m looking for?
I have the screws so someone can just copy them…just make them longer

Thanks

Btw I have contacted the manufacture and they only have one length

pictures could be helpful. Is there any possibility of drilling/retapping for a larger diameter regular screw? Or filling/retapping also using a regular screw? Pics would really help in seeing what actually needs to be fastened and how and perhaps an entirely better solution can be had.

I had a similar issue check out the bolt I needed for an idler pulley setup for my supercharger: 051-107 $92.00 Adjuster Bolt - T Head

When I called on the phone and got the price I laughed and asked them if it was made out of adamantium. Need less to say 3 dollar bolts, a bit of welding, a bit of grinding, a bit of drilling, then tapping the head of the bolt to accept an adjuster screw through it saved me some coin. I made 3 of them in about a half hour for total cost of 9 bucks. These companies and their specialty shit is a joke.

i use mcmastercarr alot if you didnt check there yet

How about Fastenal or North State Supply?
