Socket head cap screw references
 

What in the name of holly existence does #10-32 mean? I live in a country where screws are only sold using the reference to their diameter, pitch and length. How can I know what the 10-32 screw is?

RE: Socket head cap screw references
 

#10 is the Dia (wire size) 32 Is the number of threads per in.

So that means that I have to find this screw in American size, I cant use a metric screw, right?

RE: Socket head cap screw references
 

Metric size is a tad larger than 4.9mm(6 thou) If yo can you could tap it out to 5mm.

Thanks Ghost, I'd rather look for the right screw, it will secure an aluminum spinner which I don't want to risk.

They are available from Tower Hobbies in various lengths and are relative inexpensive.

RE: Socket head cap screw references
 

Oh please don't order screws and fasteners from Tower. They are so expensive like that.

Thanks Ken, I could start my own store here in Colombia with the quantities that they sell at Microfasteners :)

I have to go scout the local auto shops where they will sure have them because ordering those from the U.S would be ridiculously pricey (even from Microfasteners or RTL) and would take more time than I'm willing to wait :D



I only found two results for 10-32 screws at Tower. They are Goldberg branded but as I mentioned, ordering 1 screw from the U.S all the way down to here would be pointless. The only reason for doing so would be to order 5000 from Microfasteners and open a store as Ken suggested ;)

Never thought about the shoe being on the other foot before, good to see though!!:D When I was still working on cars, depending on where the different parts were manufactured I had to have American and Metric on hand at all times plus all the different wrench sets. Too funny!!!:):):)

RE: Socket head cap screw references
 

It's a headache, why wont everyone standardize their products to ISO standard which I believe is metric? Inches are absolutely medieval.

RE: Socket head cap screw references
 

It'll happen..from memory there are only 3 countries in the world that still don't use metrics. Two of them are little African countries and the third one is..ummmm....now where was it.....errrrrr :D

RE: Socket head cap screw references
 

You can't simply just remove it becuase it's embeded in everything.
Just becuase your toys are imported dosen't mean the US miliatry import it's hardware.

Lets just say, the US wants to repair some of it's bridges and highway.
It would be screwie if they can't get replacement bolts or screws.lmao.

You can identify metric verse SAE via the markings on the head of bolts.

There's also different grades. Example #2,#4,#8 . The higher the stronger.
Theres different types of material of course...zich, stainless steal, heat treated...ect.

When you get into constructions, you'll have to learn how to measure or calculate in decimals.:)
When you get into electronics...now, that's really fun. You'll see all kinds.

Tubbing size gose by OD, Plumbing/pipes size gose by ID...stuff like that too.lol
Wires are backwards...the greater the guage the smaller the wire.lol

The markings of how electricity is also backwards.. The electrons travel from atoms to atoms.
Therefore electricity travel from negative to positive.:)...not the otherway.

RE: Socket head cap screw references
 

They'll never convert the entire USA to metric as long as I own a ruler.

RE: Socket head cap screw references
 

Me TOO! a meter is used to measure water and electricity usage not screws, and how many is a mili anyway?

RE: Socket head cap screw references
 

Yet many other countries did exactly that...

Why do we insist on using a system based upon some englishman's smelly foot, instead of something far more logical?


It's a PITA to have to deal with both standards with planes all the time.

RE: Socket head cap screw references
 

You'll get over it. And just how do know that foot was smelly?:D

RE: Socket head cap screw references
 

Those are "grade" numbers. You might assemble a shelving set with lower grade hardware but for something like auto chassis assembly you would want a Grade 8 or better.

Some aspects of metric would be easier but just like SAE hardware there are a multiple of sizes and pitches (threads per cm)

RE: Socket head cap screw references
 

Like 1/4 of the planet's circumference? Yeah, that makes sense.:eek:

RE: Socket head cap screw references
 

For those that forget, the US did try to slowly go into the metric system in the 70s but only those of us that were 20 something or younger could figure out how to move that little dot back and forth. MOst schools didn't teach it until the early 60s.
Today we still have A lot of left overs from that little error in history. Try to buy A quart of soda. :eek: I can still remember working on my bikes and needing three different types of wrenches depending on where the bike was built.
That was no big deal, it was when I was working on something like A Dodge and needing two different wrench sets close to hand.
I can go either way, the metric system just makes too much sense but it gave my folks fits!!:D

RE: Socket head cap screw references
 

I know...I'll infest in a milling maching just for the break away bolts for fire hydrants alone.
I'll be a billionair just replacing those bolts and nuts.
I'll have to send a lobbiest to washington first ..thou.
More gasoline taxes. That sounds good.lol :)
If that goes will...I'll get them to replace the bolts and nuts for street/highway signs...then I'll work my way into gruad rails.:D

well..If I get luckie and get a military contract..I'll be a trillioniar.lol
I've seen warehouse full of creates and create of screws and nuts. Some screws go for $100+ each.lmao

But the US Highway Tranportation department dosn't have enough funds to repair it's highways and brigdes enough as it is.

RE: Socket head cap screw references
 

Creates? Are those anything like "crates"?:D

RE: Socket head cap screw references
 

Love those Wentworth wrenches, BSA and Triumph if I recall correctly. Size measured from tip to tip across bolt/nut instead of flat to flat.

Just get a Ford wrench.:D http://www.mytoolstore.com/diamond/dmdpage.html

RE: Socket head cap screw references
 

Sorry guys. After all these years I've discovered the metric system is just another solution to the same problem.

I'm personally sick and tired of litres, mm, and cm. Just one big PITA. I'll take quarts, (Fifth's), gallons, ounces, pounds, inches, and feet thank you.

Regards,

Clay

By the way, 10-32 is also 3/16 fine thread. 3/16 course is 24 tpi just to add to the confusion:D Any industrial supplier will have them too.

RE: Socket head cap screw references
 

Yeah I finally found them as 3/16 rosca fina which translates to fine thread :D
