Default Source for bolts

What the best place to order screws? I'm looking for 5/32-32, 1/2 length with hex head?

I believe we'd call that a "8-32 x 1/2 cap head screw" here in the states,, just about any hobby shop sells those.

Micro Fasteners is my go-to source. Good prices, good service, quick shipping. I recommend them.

I've been using Bold Depot recently. They'll sell from one bolt to whatever you need. I've have had very good service over a couple orders. Highly recommend them. https://www.boltdepot.com/Default.aspx

Thanks, for the leads, but they don't carry the size I need. I'm still looking?

Ah..... so you are assuming the manufacturer gave you the right size?

I'm not assuming anything! I tries 3mm,3.5mm and 4mm and 2-56, 4-40, 6-32 and 8-32. I got a picture of the box that the manufacturer uses!

OK, just seems like a weird size. What's the screw used for?

British Standard Whitworth 5/32 by 32 TPI. Link posted. Note the thread form is rounded at the crest and root. American Standard are sharp even if the same diameter and pitch they will not fit but jam and lock in place usually snapping the bolt.

https://en.wikipedia.org/wiki/Britis...dard_Whitworth

My suggestion is to re-tap and use 8-32 American Standard if you have the room. A slightly larger bolt.

The 5/32 by 32 has a tap drill size of #30 tap drill or .128

The 6-32 uses a #36 tap drill or .106 so you can see the hole is already oversize so that would make the thread sloppy and a poor fit

8-32 requires a #29 tap drill at .136 so you could run the #29 drill down each hole and re-tap it with an 8-32 tap then you could easily find screws just about anywhere. You might even get lucky and just have to run the tap down the holes depending on the material. Be careful not to apply to much force lest you break the tap off in the hole.

My recommendation is to buy the 8-32 tap and #29 tap drill and rework it for the right length 8-32 bolt.

I know I have the option to tap, but I hate to do it on a new, finished plane. That has not made its maiden flight.

Look this stuff about altering a new plane before its first flight is ...........well I can only say silly. I have yet to build anything without improving or altering something to make it better and more service friendly. I usually ditch most if not all of the hardware in favour of US standard. I don't know if its true or not but I have heard these off shore companies are famous for buying up obscure hardware and using it in their kits because they get it for pennies. When its gone they look for something else to do the job. No consideration for the poor sucker who is trying to replace any broken or missing stuff. You may find this out if you were to contact them about replacing this hard to find stuff.

Your going to open up the minor diameter a few thousands and the tap you will be putting down is the same thread pitch how hard can it be???????

11 bucks an eye bolt man you can buy the drill, tap and a couple of dozen bolts for that price.

Have at it and good luck.

I've got to agree with Propworn. It's not a big deal. We do this all the time when setting up a new plane. The cost is immaterial K.I.S.S. principle. Keep It Simple Stupid. Right?

Personally, I'd take the advice above and re-tap for an 8-32 screw and be done with it. That said, here's a couple links to some 5/32 BSW screws.
