aye ,me screws round here all have heads , whereas a threaded rod thats lost its head is a "grub screw)

Nuts & Bolts
The defining distinction, per Machinery's Handbook,[2] is in their intended purpose: Bolts are for the assembly of two unthreaded components, with the aid of a nut. Screws in contrast are used with components, at least one of which contains its own internal thread, which even may be formed by the installation of the screw itself. Many threaded fasteners can be described as either screws or bolts, depending on how they are used.

Set screw
A set screw is a type of screw generally used to secure an object within or against another object, normally not using a nut (see bolts compared with screws). The most common examples are securing a pulley or gear to a shaft. Set screws are usually headless (also called blind), meaning that the screw is fully threaded and has no head projecting past the major diameter of the screw thread.

PS
A threaded rod is called studding.

Go into a nut and bolt supplier ,I can send you a linky ,ask for a box of m8 x 75 bolts , when produced say you want threads all way up and see what he says ....you can quote as many links as you like to all kinds if engineering fixings , none if which are relevant to this thread. I and others speak from practical experience not web links , sadly some folks never grasp that so remain in the position they are ,can't add smilies as I'm on the phone.......

Or All thread, Screwed Rod, Long thread and probably a lot more depending where you are in the country. It's the fastening equivalent of the bread cob.

And most will say "Inner or outer" by which they mean a box of say 100 or a box of boxes of 100 I cut my teeth dealing with Williams Bros in Sheffield where every type of fastener had it's own counter ... bright, black, metric (then a very small lean-to shed) etc etc. You soon learned or spend a VERY long time following different coloured lines on the floor in and out of semi-derelict warehouses to find the next item on your list, usually to have to go back from whence you came.

As in designing tooling for vehicles that quite a few members of this forum have probably had in their vehicles in the past. Not to mention pharmaceutical products that they don't even know about. Or the disposable airline products ..........

JustKampers do a kit of the right parts especially for this job. It also contains a flat plastic part which I am not sure what to do with. It doesn't appear in any parts catalogue I can find, not even their own!

Hey, stevelane, I bet you wish you hadn't asked now

I remember Willims Bros well. It was fastener heaven.
I was once quoted a fortune for a set of cylinder head stretch bolts from droF. I went to williams not very hopefull for such a specialist bit, I followed the correct colour coded paint line and got to the counter bolt in hand. Before I'd had a chance to say anything the guy serving reached under the counter and produced said item. And they cost the change in my pocket!
They moved to a new building in Don Valley and were never the same again.
There were loads of specialist suppliers in Sheffield If you could find them in the back streets, and most of them realy helpfull to idiot members of the public like me.

I just had to replace my right hand end cap twice in 2 months Other bliddy drivers in parking situations I wasn't even moving on either occasion, but I was in the van (luckily). Twice in 8 weeks !!!!!!!!!!!!!!!!!!!!!!

And my "captive nut" is missing (Thanks again John Williams Auto Body of Chester ) and you are right, as far as I can see, it's impossible to get behind there to fit a nut on that bolt without removing the bumper, at least partially. I won't tell you the workaround I have used

What did you expect from a bunch of people who can't even agree if they own a T25 or a (T3)


















It's a T3 BTW

My latest project at work in the real world, the accuracy and speed is amazing, four on order @20k each. Beats metal bashing

Temporarily bolted down with NUTS and BOLTS

My wife asked what the fuss was, so I asked her what was the difference between a screw and a bolt, she said "obvious, a screw screws into a hole, a bolt screws into nut" AND SHE'S FROM ESSEX

That was a homage to ....... 6 nuts

Whilst doing my apprenticeship at a general and marine engineering firm, I quick had to learn the difference between screws and bolts. You always got what you asked for and if you asked wrong then you got a sinking in an inhibiting tank...

Asked or specified, what apprenticeship? And when?

Had riv nuts fitted in place of clinch nuts on a job today, can't use them because they are not flush. Shame the sheet metal company didn't know the difference.
