OMEN by HP Desktop PC 500-157c Product Page

http://support.hp.com/us-en/product/OMEN-by-HP-Desktop-PC/12079703/model/12740644/manuals

 

The hard drives "slide" into the hard drive bays.

HP uses a special "Cheese / Fillister Head" 6-32 machine screw with

a Torx T-15/Slot head as the "guide screw" for the HDD bays.

http://h10032.www1.hp.com/ctg/Manual/c05185432

 

HP does not sell these specific Cheese / Fillister Head screws to end-users (HP mgt. decision).

Compaq computers original used this type of screw for a decade (1990s), before the HP merger.

This question is asked in this HP Support Forum (Hardware) at least once each week.

 

I purchase these 6x32 screws for HP cases, on eBay, from the numerous surplus and parts houses.  

Here is one reseller: http://www.ebay.com/usr/entermediaplus?_trksid=p2385738.m2547.l7859

 

NOTE: The Optical Drive, ODD, DVD/CD screws are NOT the same.  

Those are METRIC, M3 and harder to source -- but do appear on eBay.

 

IF you are installing a 2.5 SSD, then the part number ( 654540-002 ) provided by the "MrRobot" is useful as an adapter carrier for the 3.5" hard drive bays.

WATCH Pricing, and note delivery times (China is normally 2+ weeks).

@btrbcomposer and @beatgr,

The specific screws are called "Fillister Head". I have mentioned this several times.

For the HDD mounting HP uses the machine screw, 6-32, 1/4" (0.25 inch) length, zinc plated steel.  DO NOT use longer length screws, which can damage the PC control boards of many hard drives.

 

There are SOME HP cases (Slimline s5000) that use a shorter version (3/16") for specific areas, this is noted in their user guides.

--

Dean's link provided to Grainger is for a Nylon screw, which I do not recommend

The specific head on the HP OEM screw is neither Cheese or Fillister (by standard definition of machine screws), Zinc plated steel is best.  HP OEM screws (6-32, 1/4") pictured below.

@beatgr,

Thanks for the update on metal Fillisters.  When I went to Fastenal (to sepc the screws form a HP 860), the price was $5 for only 4 screws.  That was years ago.  The nylon screws would work.

BTW, Grainger has them in 3/16 length (but it's still nylon). 500 less than $5.

Dean,

 

It is frustrating .... when the HP/Compaq Torx/Slot 6-32 screw is a combination of both machine screw standards.  FLAT head, (like Cheese), and a Larger Height to Diameter ratio (like Fillister).

 

Cheese has a Flat head -- BUT the head's height is normally "half the head diameter".

Fillister has a Convex (domed) head -- BUT its Height to diameter ratio is "larger than cheese head".

 

McMaster-Carr HQ (and their Chicago "Will Call" door) is about one mile from my house.

Torx head screws

https://www.mcmaster.com/#torx-machine-screws/=16kgoaj

They looked at it, a few years ago, ... and determined it was built "per a Compaq spec",

at least 25+ years ago.

This looks like the most likely answer,, from what I can see of the other drives without pulling them out.  HP store says that they are not YET available for sale, which I hope implies that they will be eventually.

 

Thanks all for the help.

"654540-002 Bracket Assembly - Hard Drive 2.5 into 3.5 Universal Single Drive"

 

You can buy that specific part (New and Used) directly from China, or via eBay, Amazon, Alibaba.

WATCH Pricing (and shipping times) ... varies Wildly !!  

 

Note: There are HP 654450-001 and 654540-002 versions for sale.
