I need the name of the screw for the HP quick deploy rail kit. The screw clicks into the square holes of the rack. It is a Gen4 Rail kit but the screw is like the Gen8 Rail kit ones. I called HP support, but they couldn't really help me. Unfortunately the rack manual does not name this screw either.

After googling a while, I found the compatible "Thumb Style Rack Screws". It would do the job but isn't exactly what I am looking for.

So, what is the name of the pictured screw.

The photo you've posted doesn't provide a clear picture of what you're doing or need. You appear to require the four guide pins that sit on the inside face of the quick-deploy rail kit. There are EIGHT per rail arm (for 2U and bigger servers. FOUR per arm on 1U systems). The only reason these would ever be removed is if the rails were installed in a 4-post threaded round-hole rack.

You haven't given good context on what you're trying to do, so that's why you haven't had good answers... It leaves us guessing... Why are the pins missing?

Scenarios:

  • You broke(?) the existing pins and you need one or more. Call your server vendor and describe the part you're looking for.
  • You're missing a lot of the screws because someone removed them. Buy some used rail kits or go back to whoever sold you the equipment.

You can refer to these as "guide pins" and obtain them from HP, an HP vendor, or a used-server parts dealer if you need them.

Edit: They're definitely called "Guide Pins". See the HP video.

  • The rail kits are installed in a 4-post threaded round-hole rack and now I want to use this rail kits in a square hole rack. I can't believe that this screw has not a part-number. This kind of screw was built in rail kits since Gen3 i think and cant believe I am the first person in the world who need this screws. – kockiren Dec 11 '12 at 13:23
  • You're not. But where did the screws go? – ewwhite Dec 11 '12 at 13:23

    I do not know where the screws are. That is the reason why i need new screws. – kockiren Dec 11 '12 at 13:25
  • What happened between the time when you didn't need the screws and now, the time where you need the screws? Did your organization change all of the racks in the environment? – ewwhite Dec 11 '12 at 14:39
  • I need the screw now there is no time between i didn't need and now?! – kockiren Dec 11 '12 at 15:19
  • I guess he bought a bunch of these kits some of which missing those screws. Whatever is the reason for demanding them - who cares? I don't... If you was the person wanting to get/buy some of these, a name would be handy. I remember lots of different types of screws for Rhode&Schwartz equipment. They all had names and part numbers - and the manufacturer will know them. – mbx Dec 11 '12 at 15:31

    The point is that these screws come attached to the rail kits. An explicit and deliberate action is needed to remove them from the rails. They are not available separately. Perhaps some clue as to why they were removed may help in finding a source for them. I've even checked with my parts providers. We can get them in small quantities, but not 128 pieces. – ewwhite Dec 11 '12 at 15:38

    I suspect the reason will involve the "fog of war". If you can lose a server-lift (sigh), you can lose a screw. – Sirex Dec 11 '12 at 23:15
  • When you checked your part provider what do you ask them? How many your provider can order? If I can order a small quantity then i get a part number maybe. – kockiren Dec 12 '12 at 06:35
  • @kockiren My parts suppliers can't order those parts individually. They were only able to cannibalize a few from leftover rail kits. – ewwhite Dec 12 '12 at 09:25
  • @kockiren Did this answer your question? – ewwhite Jan 20 '13 at 12:25
  • This helped me but this is not the answer. I take the "Thumb Style Rack Screws" now and it works. But it seems to be impossible to get exactly this screw :-( – kockiren May 29 '13 at 11:44

Such custom screws don't have a standard name. The manufacturer may or may not have it's own name for it (normally not) but only they can tell you. Regardless of whether it has a name or not, what you really need is a part number, as only that can uniquely identify the item. Either way, you need to talk to HP about this.

What makes you think it must have a specific name ?

If the manufacturor doesn't give it a name, it officially doesn't have one.

If you refer to it as a 4th Generation HP Quick Deploy Rack Screw, I doubt many people would misunderstand your meaning.
