tap end stud

Or "flanged tap end stud" if they are like the ones in the following French site:

Picture at: http://www.hd19.net/restauration/DS19 1960/DS19_1960_EPISODE...

They appear to be a bolt that is threaded at both ends, with a central unthreaded section separated from the threaded ends by flanges. I know I HAVE come across a name for these things, but whether I can find it again ...

Tap End Studs (For Studded Flanges) -
Studs threaded on each end with an unthreaded portion on the body diameter. The thread length dimension on one end controls the depth that that end will engage into a tapped hole, and also controls the extension length of the stud beyond a studded flange

The studs you want have the proper name "Tap End Studs." Studs of this type have threads cut to a specific length on one end to control the extent of engagement in a tapped hole. Properly dimensioned studs of this type tighten at the top of the hole where the thread ends, the remainder of the stud extends outward the proper length to engage a mating flange and accept a nut.

agree narasimha (X) : long stud with both ends threaded

agree Charles Hawtrey (X) : That's the type of stud that's used for holding on a car engine cylinder head, especially a flat head (side valve engine) head//Never had that, but YNK. Never knew its name, either - just called it 'stud' before.

Yeah, and the things are buggers to get out when they shear off inside the block.

(brake caliper) retaining screw

En visitant: http://www.forum-auto.com/pole-technique/section12/sujet4483...

j'ai trouvé je site "devisser la vis colonette qui tiens l'etrier en bas. La devisser avec une clé de 13 et tenir la partie mobile avec une clé de 15"

J'ai aussi visité : http://www.yaronet.com/posts.php?s=97829 qui donne :

La vis colonette
Elle est vissée en bout de boîte,traverse le support caoutchouté et un écrou est vissé dessus,(sous la batterie)
Après avoir placé un support moteur (cric +cale sous le carter ou élingue),on dépose l'écrou,
On démonte le support caoutchouté :2 écrous de 13,
La vis colonette apparaît alors,La partie inférieure comporte des facettes qui permettent l'utilisation d'une clé à pipe de 16 à 6 pans , creuse,Elle peut-être dure à dévisser si du frein filet a été utilisé au montage,

ce qui me fait penser à "retaining screw"

mais je reste un profane en ce qui concerne ce domaine...

Je pense qu'il s'agit de :"mounting bolt"

Reference:

In support of the answer from "Bourth" above.
The first page of http://www.citdoks.de/Bilder/225/volumeI-2.pdf shows such a thing at item 3, as listed on page 2.
This site gives "shouldered stud" as the English equivalent, but I prefer "tap end stud" as defined here:
http://www.specialbolts.net/fastenerterms3.htm

"Tap End Stud: A double-end stud having each end threaded for a different class of fit. The tap end has a Class 5 fit to produce an interference fit in a tapped hole for semi-permanent assembly. The nut end is threaded Class 2A for assembly with a standard nut."
