vis de blocage captive


Explanation:
Les vis captives de Southco permettent de rassembler des panneaux grâce à la fiabilité éprouvée d'un raccord fileté. En position ouverte, elles restent bien solidaire du panneau extérieur, empêchant la perte de matériel et permettant un assemblage rapide. - https://southco.com/fr_eu_int/fasteners/captive-screws

blocage de la vis imperdable


Explanation:
Ici "lock" est represente une action, pas un objet. Une "captive screw" est une vis imperdable comme le dis Tony.

disagree  Tony M: Yes, but this does not reflect the s/t — it is the 'lock' that is 'captive', not the screw itself. But in any case, Asker's added context now renders this inapplicable. The 'captive' here means it is retained in place, not that it can't come off.

bloc-vis imperdable


Explanation:
Again, just a word-for-word guess, but to help you get the correct interpretation of the s/t

I've often seen 'imperdable' used for 'captive' in this sort of sense, which I think is preferable to the direct anglicism.

However, without more context, it's hard to tell just what type of 'screw' this is — your wider context may guide you.

Clearly, now we have proper context, my suggestion is no longer relevant!

neutral  Daryo: "imperdable" would more be the type of screws that stay attached to the cover when you unscrew them to remove the cover? // You don't make a screw "imperdable" by high friction, but by changing the shape between the head and the rest of the screw.
8 hrs
  -> Generally, that is what 'captive' means, and I've seen the FR term used even in senses where there is no such actual attachment. / Absolutely! But as I've already said, the extra context renders my suggestion irrelevant anyway. Hindsight's wonderful!

fermeture à vis imperdable


Explanation:
Of course we have no context, but I read this as 'captive-screw lock' (with a hyphen) meaning a device for locking/holding closed/retaining that consists at least in large part of a captive screw.

I have such things securing the removable (easily) side panels of my heat pump. The slotted flat-head plastic 'screws' (they have a minimal thread at the end, but enough to hold the panel in place) are held captive in the side panel by means of spring clips (I had to replace one recently when it rusted out; had to get a bag of 50 of the blighters).

I've not actually found any examples of fermeture à vis imperdable but the answer above still fits.

The closest I have come in terms of actual physical evidence is:

Les fixations de panneau MONADLOCK™ offrent une conception à vis captive, résistante aux vibrations et à de nombreux cycles de pose."
https://www.lisi-aerospace.com/fr/product/fixations-de-panne...

I've tried with other words like verrouillage, maintien, fixation, attache to no avail, even if such words are found in abundance in texts such as this:

"What are Vis captives ?
La principale caractéristique d'une vis captive est sa capacité à maintenir en permanence une rondelle captive spécialisée « captive » sur sa partie non filetée. Accu se spécialise dans la conception, la fabrication et le support de fixations captives usinées de haute précision. Une rondelle captive sert de retenue, verrouillant ces composants en place. Les attaches captives assurent une liaison sûre et évitent la perte ou l'endommagement de l'attache au sein d'un assemblage en ne permettant pas de démonter complètement la vis.

Ces composants peuvent être utilisés pour fixer des panneaux en tôle ou en captivité, qui sont généralement retenus pour des raisons de sécurité. La tôle ou le panneau est maintenu en place entre la tête de la vis et une rondelle captive, ce qui empêche son retrait complet."

agree  FPC: Also. Provided there's a hidden hyphen (hence the noun phrase is adjectivized)
45 mins
  -> Thanks. So many people are oblivious to the importance of hyphens.
disagree  Daryo: we have more than enough context to be sure that this ST is not about that kind of screws - THAT kind of method for avoiding misplacing screws has NOTHING to do with "keeping the screw in position by means of high friction"
21 hrs
disagree  Tony M: This is a kind of screw-locking device that remains 'captive' within the threaded element.

avec freinage interne


Explanation:
There has been a mistranslation from German to English.

Now that I've seen we are dealing with thread inserts, things take on a different turn (joke) to my previous answer. I also see the manufacturer is German, and that what has been translated as 'captive screw lock' is Schraubeverliersicherung or something like 'insurance against screw loss'. This covers not holding a screw captive (in a cover plate, for instance) but ensuring its threads do not succumb to loosening. This can involve formschlüssige Elemente, something like 'parts matching by shape'), and klemmende Elemente, or something like 'friction-fit parts' which can include the plastic inserts in lock nuts, for instance.

In a text on Loctite we find that Verliersicherung:
"LOCTITE Schraubensicherungen sind den herkömmlichen mechanischen Methoden weit überlegen
• Mechanische Sicherungselemente, z. B. Splinte, Sicherungsbleche: Sie wirken lediglich als Verliersicherung für Muttern und Schrauben."
is translated as 'prevention of loosening':
"LOCTITE Threadlockers are superior to traditional mechanical locking methods
Mechanical devices, e.g. split pins and tab washers; Only used to prevent the loss of nuts and bolts from loosening."

The Schraubeverliersicherung function of the thread inserts is an 'anti-loosening' (freinage) function (for the screw in the insert, not for the insert in the body of metal). The German manufacturer's 'screwlock' (note the spelling, which could otherwise be 'screw-lock') thread inserts have a feature that exerts a grip on the screw threaded into it — " The screw lock is achieved by one or more polygonal turns that have a clamping effect on the flanks of the installed screw' — unlike its 'free running' (I would say 'free-running') inserts from which screws can be removed without exceptional effort.

Now, freinage is exactly what we find on the manufacturer's site:

"HELICOIL® Plus Screwlock
Ce filet rapporté dispose d’un système de freinage interne qui s’oppose au dévissage de la vis. Une ou plusieurs spires polygonales serrent les flancs du filet de la vis pour la bloquer."
https://www.boellhoff.com/fr-fr/produits-et-services/element...

So for 'thread insert with captive screw lock', which I believe is your fuller text, I would say filet rapporté avec freinage interne.

une vis qui ne va pas se dévisser d'elle-même / qui tient ferme


Explanation:
Not sure what's the right technical term, but sure that it's what it means.

La vis est immobilisée en place par friction, et ne va pas se dévisser toute seule


[The polygonal twist of the HELICOIL® Screwlock results in] a high friction locking capacity and thus a captive screw lock.
=>
[...] une capacité élevée d'immobilisation par friction et donc une vis qui ne va pas se dévisser d'elle-même / qui tient ferme

neutral  Tony M: Yes, it's much easier with proper context! However, do note that here we are talking about the lock and not the screw itself.
1 hr
  -> the way "Captive screw lock" was used in given samples indicates that it means "the screw being locked in position" as opposed to being "loose" or "being prone to unscrewing" IOW "lock" is not a device.
neutral  FPC: It's either a device or its function to keep a screw tightened (either an actual captive screw or any screw with captive-like fastness). Not the screw itself..
4 hrs
  -> it's NEITHER - "Captive screw lock" describes the "status" of the the screw "being locked in position" - read samples given by Asker.
